How to install an air filter

Install air filter

After cleaning the filter element, install each part in the reverse order of removal. The filter element must be securely mounted. It is not advisable to touch the paper part of the filter element with your hands or utensils. In particular, the oil cannot contaminate the filter element. When the intake pipe is installed, its sealing should be ensured, and the sealing of the air inlet joint jacket must be especially noted. When maintaining the air filter, the condition of the hose connected to the air filter should also be carefully checked. If any crack or aging of the hose is found, the hose should be replaced. Clean the air filter and replace the filter if necessary. The car engine is a very delicate part. Minimal impurities can damage the engine. Therefore, before entering the cylinder, the air must be carefully filtered by the air filter to enter the cylinder. The air filter is the patron saint of the engine. The condition of the air filter is related to the life of the engine. If a dirty air filter is used during driving, engine intake will be insufficient, resulting in incomplete combustion of the fuel, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air filter clean. Under normal road conditions, the air filter must be cleaned and maintained for 7500-8000km. The interval of maintenance in areas with large dust levels should be shortened accordingly. Dry air filters are widely used on new cars. The filter elements of dry air filters are made of resin-treated microporous filter paper, which has the advantages of good filtration and easy maintenance. Because of different models, their structural shapes are different, but their maintenance methods are basically the same. When it is being maintained, it should be carried out in accordance with the use mileage specified by the automobile manufacturer.

Four-stroke engine

Four-stroke cycle used in gasoline/petrol engines. 1 = Intake, 2 = Compression, 3 = Power, 4 = Exhaust. The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:

Intake: also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston
Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage.
Combustion: also known as power or ignition This is the start of the second revolution of the four stroke cycle. At this point the crankshaft has completed a full 360 degree revolution. While the piston is at T.D.C. (the end of the compression stroke) the compressed air-fuel mixture is ignited by a spark plug (in a gasoline engine) or by heat generated by high compression (diesel engines), forcefully returning the piston to B.D.C. This stroke produces mechanical work from the engine to turn the crankshaft.
Exhaust: also known as outlet. During the exhaust stroke, the piston once again returns from B.D.C. to T.D.C. while the exhaust valve is open. This action expels the spent air-fuel mixture through the exhaust valve.

cylinder block

The cylinder block is an integrated structure comprising the cylinder(s) of a reciprocating engine and often some or all of their associated surrounding structures (coolant passages, intake and exhaust passages and ports, and crankcase). The term engine block is often used synonymously with “cylinder block” (although technically distinctions can be made between en bloc cylinders as a discrete unit versus engine block designs with yet more integration that comprise the crankcase as well).

In the basic terms of machine elements, the various main parts of an engine (such as cylinder(s), cylinder head(s), coolant passages, intake and exhaust passages, and crankcase) are conceptually distinct, and these items can all be made as discrete pieces that are bolted together. Such construction was very widespread in the early decades of the commercialization of internal combustion engines (1880s to 1920s), and it is still sometimes used in certain applications where it remains advantageous (especially very large engines, but also some small engines). However, it is no longer the normal way of building most petrol engines and diesel engines, because for any given engine configuration, there are more efficient ways of designing for manufacture (and also for maintenance and repair). These generally involve integrating multiple machine elements into one discrete part, and doing the making (such as casting, stamping, and machining) for multiple elements in one setup with one machine coordinate system (of a machine tool or other piece of manufacturing machinery). This yields lower unit cost of production (and/or maintenance and repair).

Today most engines for cars, trucks, buses, tractors, and so on are built with fairly highly integrated design, so the words “monobloc” and “en bloc” are seldom used in describing them; such construction is often implicit. Thus “engine block”, “cylinder block”, or simply “block” are the terms likely to be heard in the garage or on the street.

Piston ring number and fire shore

1, the number of piston rings

In recent years, in order to reduce the friction work, improve the mechanical efficiency, reduce the height of the ring area to shorten the piston compression height and total height, piston ring number decreases. From the thirties of 5 to 6 ring groove development to 2 to 3 ring groove. It has been found that more than one compression ring is not necessary because once the upper compression ring fails, the other compression rings can not seal the gas in the combustion chamber so that it does not leak into the crankcase and can not control the oil rising upward along the cylinder wall Into the combustion chamber. So instead of increasing the number of piston rings, it is better to take measures to improve the performance of the piston ring, with a compression ring and two oil grooves to ensure the completion of sealed gas and oil control role.

2, fire shore

The height of the fire shore has the tendency to be properly increased, especially the semi-split combustion chamber diesel engine with the combustion chamber arranged inside the piston top. In order to prevent the top ring of carbon deposition and adhesive, but also requires the first ring groove temperature can not be too high, for this reason, in addition to using ring groove set ring, the fire shore there is a long trend, but the more the degree of strengthening the more obvious this trend .

In order to reduce the intense heating of the first ring groove gas, diesel engine piston, often on the shore of the firepower car out of the spiral shallow groove, the use of maze step-down principle to reduce gas along the piston and cylinder liner clearance channeling.


Car air filter effect

Automotive air filter is mainly responsible for the removal of particulate matter in the air of the device. Piston machinery (internal combustion engines, reciprocating compressors, etc.) work, if inhaled air contains impurities such as dust will exacerbate the wear parts, it must be equipped with air filters. Air filter by the filter and the shell of two parts. The main requirements of the air filter is high filtration efficiency, low flow resistance, can be used continuously for a long time without maintenance.

Car engine is a very precise mechanical parts, the smallest impurities will damage the engine. Therefore, before entering the cylinder, the air must pass through the fine filter of the air filter to enter the cylinder. Air filter is the patron saint of the engine, the state of the air filter is related to the quality of the engine’s life expectancy. If the car is running dirty air filter, the engine will be insufficient intake, the fuel combustion is not complete, leading to unstable engine work, power decline, fuel consumption increased phenomenon. Therefore, the car must keep the air cleaner clean.

Recoil start

Recoil start (also called manual start, pull start or rewind start) is a method of starting an internal combustion engine, usually on small machines, such as lawn mowers, chainsaws, ultralight aircraft, small outboard motors and portable engine-generators. Recoil start is also used on some small vehicles such as small go-karts, minibikes, and small ATVs.

Modern version
The starter mechanism comprises a rope, with a grip at the end, moulded rope reels and a spring. The rope is coiled within a reel which is held under spring tension within an outer reel. This reel assembly is in contact with one end of the crankshaft through a ratcheting mechanism (specifically, a freewheel clutch. When the rope’s grip is pulled, the rope uncoils, tensions the spring, engages the clutch and turns the crankshaft, spinning it to crank or start the engine before the end of the pull stroke. After the end of the pull is reached, the spring operated reel[1] retracts the rope, either to store it, or to prepare it for another attempt to start and disengages the clutch hence the term “re-coil starter”. If the reel were directly connected to the crank and lacked the freewheel mechanism, once the rope reached its end, the spinning crankshaft would keep turning the reel, which would violently recoil the rope in the opposite direction until it reached its end, where it would likely jam and stall the engine.

Old version
There is an older, simpler version of pull starter that has a reel directly connected to the crankshaft, and a rope that is not connected to the reel. The rope is wound around the reel and pulled, starting the engine, but once the end of the pull is reached, it comes free, leaving a loose rope in the person’s hand. If the engine fails to start on the first pull, the operator has to re-wind it by hand. This is also done when the engine is shut down to prepare it for the next start (this is technically not a recoil starter, since it doesn’t re-coil the rope; both are actually forms of pull starter).


Black technology coming? Honda push piston variable stroke technology

Recently, according to foreign media reports, Honda registered a new engine patent, its greatest feature is a piston variable stroke, making each cylinder can have different performance.

According to the previous engine working principle, assuming that this is a 2.0L four-cylinder engine, then it should be the size of each cylinder is 500cc, if you want to make the cylinder to work on demand, then according to the number of cylinder work, Only 500cc, 1000cc, 1500cc and 2000cc these four cases.

The new engine technology allows each cylinder piston to have a different stroke through a change in crankshaft radius, thus allowing each cylinder to operate at a different “displacement,” and it is learned that it will provide up to 15 different combinations of In other words, the same 2.0L four-cylinder engine, if the application of the technology then there are 15 different performance.

From the description of the new patent, it can be used in two-cylinder, three-cylinder, four-cylinder and V6 engines. Honda has yet to announce more details of the technology, but foreign media predict it will mainly improve fuel economy, or perhaps in the near future, we can usher in the mass production of the system.

What are the features of the cylinder assembly?

1) Cylinder

Cylinder diameter represents the size of the cylinder output force. Pistons in the cylinder to make a smooth reciprocating sliding cylinder surface roughness of the inner surface should reach Ra0.8μm.

SMC, CM2 cylinder piston seal with a combination of two-way seal, piston and piston rod with a rivet link, without nuts.

2) End cap

Exhaust exhaust port is provided on the end cap, and some are also provided with a buffer mechanism in the end cap. The rod side end cap is provided with seals and wiper rings to prevent outward leakage from the piston rod and to prevent external dirt from mixing in the cylinder. A guide sleeve is provided on the rod side end cap to improve the guiding precision of the cylinder and bear a small amount of lateral load on the piston rod to reduce the bending amount when the piston rod extends and prolong the service life of the cylinder. Guide sleeve usually use sintered oil alloy, pouring copper casting. Malleable cast iron used in the past, in order to reduce weight and rust, often using aluminum die-casting, micro-cylinder with brass material.

3) Piston

Piston is the pressure in the cylinder parts. In order to prevent the left and right pistons around channeling gas, with piston seals. The wear ring on the piston can improve the cylinder’s guiding, reduce the wear of the piston ring and reduce the frictional resistance. Long wear-resistant ring using polyurethane, PTFE, cloth cloth synthetic resin and other materials. The width of the piston is determined by the seal size and the necessary length of the sliding part. Sliding part is too short, easy to cause early wear and tear. Piston materials commonly used aluminum and cast iron, small cylinder piston made of brass.

What is the role of car clutch2

1, to achieve a smooth shift

In the car driving process, in order to adapt to changing driving conditions, the transmission often need to change the work of different gear. Gear shift gear shift, the general is toggle gear or other gear shift agencies, so that a gear shift of the original gear launch drive, and then make another gear gear into the work. In the gear shift must be depressed before the clutch pedal, power transmission interrupted, easy to disengage the meshing deputy of the original stalls, while the new gear meshing meshing vice-paced gradually tend to synchronize, so into the engagement of the impact can be greatly Reduce, to achieve smooth shift.

2, to prevent the drive train overload

When the vehicle is in emergency braking, without the clutch, the engine will drastically reduce its speed due to its rigid connection with the driveline, so all of the moving parts will generate a large moment of inertia (which may be much larger than the value given when the engine is in normal operation Of the maximum torque), the transmission caused more than its carrying capacity of the load, leaving the mechanical damage. With the clutch, it is possible to eliminate this danger by relying on the relative motion that may be generated between the active part and the driven part of the clutch. Therefore, we need clutches to limit the maximum torque that the driveline can bear to ensure safety.

Clutches can be divided into: friction clutch, or the use of liquid as a transmission medium (ie, hydraulic coupling), or the use of magnetic transmission (ie, electromagnetic clutch.

How long should the car change the air filter

Generally speaking, if the car alarm indicator must clean air filter, when the car mileage of air filter maintenance interval mileage requirements, or air filter clogging indicator alarm (regardless of how much mileage), must clean air filter.
1) clean air filter. Loosen the lock nut fixed filter, filter, remove the cover after pull out filter. Take out the filter core and pay attention to prevent impurities falling into the carburetor. Wipe the air filter inside and outside with a rag. Check the pollution degree of the filter core and clean it. When the filter core is stored as dry dust, it can use the compressed air which is no more than 500KPa to start blowing up the dust inside and outside the filter core evenly from the inside side of the filter core. If there is no compressed air, use the handle to gently tap the filter cartridge, and brush the outer dirt with the brush. In operation, no hard knocking or collision core can be used. When cleaning, if the filter core is found to be damaged, the filter core should be replaced. The paper filter core, which is used normally, should be replaced at the specified interval.
2) check the filter core after cleaning and drying. Take the light on the inside of the filter to observe whether there is any damage, small hole or thinning part from the outside, and check whether the rubber washer is damaged or not. If there are exceptions, filter core and washer should be replaced.
3) replace the filter core of the air filter. According to the regulations of each type of vehicle, the replacement is carried out. Replace the filter, the new filter should pay attention to check whether there is any damage, whether there is a defect of washer, found defects, should be complete.
