Current motors mainly include L (in-line) motors, V-type motors, W-type motors and horizontally opposed motors. Another special feature is the rotary engine, which is a Mazda patent.
V-type engine: The cylinders of the V-type engine diverge in pairs, forming a certain angle. They look like a "V" when viewed from the side, which is why it is called a V-type engine. Compared with in-line engines, V-type engines shorten the length and height of the body, increase the rigidity of the cylinder block and reduce the weight of the engine, but increase the width of the engine and the shape is complex and difficult to process . It is generally used for 6 cylinders and engines with more than 6 cylinders. There are currently four main types of V-type engines: V6, V8, V10 and V12.
In-line engine: its cylinders are arranged in a row, that is to say in a column, hence its name. The engines inCurrent line mainly include L3, L4, L5 and L6. The cylinder block of the in-line engine is arranged in-line. The cylinder block, cylinder head and crankshaft have simple structure, low manufacturing cost, good low-speed torque characteristics, low fuel consumption, compact size and wide application. is of low power.
W-type engine: Strictly speaking, the W-type engine is still a type of V-type engine. It simply divides the cylinders on both sides of the V-type engine into two groups. like a "W" seen from the side. We can also say that the W12 engine is composed of two V6 engines. Its greatest advantage is that it has a compact and easy to arrange structure, which favors the optimization of engine compartment space. the structure is too complex. The W-type engine is Volkswagen's patented technology. Only Volkswagen, a brand owned by Volkswagen, uses engines oftype W. Currently, there are mainly W12 and W16 engines.
Horizontally opposed engine: Actually, it is also a type of V-type engine, except that the angle between its cylinders is 180 degrees. The horizontally opposed engine is a combination of automobile engines that best corresponds to the principles of sports mechanics. Its manufacturing cost and the difficulty of its process are currently quite high, only Porsche and Subaru use it in the world. The biggest advantage of the horizontally opposed engine is its low center of gravity. Because its cylinder is "flat", it not only lowers the car's center of gravity, but also allows the front of the car to be designed to be flat and low. These factors can improve the driving stability of the car. At the same time, the arrangement of horizontally opposed cylinders constitutes a symmetrical and stable structure, which makes the engine smoother than aV-type motor, and the power loss during operation is also minimal.
In addition, since the vibrations generated by the piston and crankshaft when moving left and right cancel each other, low noise and low fuel consumption are achieved. Currently, there are mainly horizontally opposed 4- and 6-cylinder engines.
Once the speed of the Yuchai supercharged engine reaches 2000, the engine suddenly sounds like it is missing a cylinder. There is no smoke or water temperature
1. Engine missing cylinder mainly comes from ignition system and fuel injection systems.
2. Spark plugs are very important. If a spark plug does not work, it can increase fuel consumption by 10-15%, reduce power by 18-35% and reduce CO and HC content. in the exhaust gases will double., the performStart-up times decrease. The spark plugs you choose are medium and high calorific value types. Choosing those with low calorific value can easily cause excessive carbon deposits on the spark plugs, once the fuel is moistened, it is equivalent to a parallel shunt. Resistance between the spark plug electrodes, causing the spark plug to leak and flash excessively, if the spark plug does not work in severe cases, it will naturally easily lead to cylinder shortage.
3. Another easy cause of cylinder starvation is the injector, an important part of fuel injection. The injector has carbon deposits and the injector filter is clogged, preventing accurate injection and atomization. the fuel injector gets stuck, causing the engine to run without a cylinder or suddenly stall. Carbon deposits in the fuel injection nozzle pcan also easily cause difficulties during cold starting.
Lack of engine cylinders mainly means that one or more engine cylinders are not working properly. Typical symptoms include: abnormal engine operation or insufficient power, erratic engine operation and rhythmic vibrations at high, medium and low speeds, black smoke coming from the muffler, and gunshots.
Running the engine without a cylinder will cause great damage:
1. Engine speed and power decrease.
2. Increase fuel consumption and pollution emissions.
3. Increases wear of running parts and shortens the life of lubricating oil.
A shortage of cylinders in the engine can cause the car to consume a lot of fuel, emit black smoke, weaken, have reduced power, the vehiclethe cannot accelerate, have severe vibration and increase driving noise. And this greatly harms driving safety. Especially on sections that require slopes, the engine load of a vehicle without a cylinder increases, the body shakes more obviously, and instant misfires are very easy to occur.
1. Fault Diagnosis:
Usually manifested by: abnormal engine operation or insufficient power, irregular engine operation at high, medium and low speeds and rhythmic vibration of the black exhaust muffler. smoke and gunshots. The phenomenon of running out of engine cylinders can cause the car to consume a lot of fuel, emit black smoke, become weak, reduce power, prevent the vehicle from accelerating, have severe shaking and increase driving noise. And this greatly harms the security ofconduct. Especially on sections that require slopes, the engine load of a vehicle without a cylinder increases, the body shakes more obviously, and instant misfires are very easy to occur.
2. Running the engine without a cylinder will cause serious damage:
1. Engine speed and power decrease.
2. Increase fuel consumption and pollution emissions.
3. Increases wear of running parts and shortens the life of lubricating oil.
3. Maintenance method: Firstly, check the circuit faults, and secondly, check the valve tightness (cylinder compression ratio). If there is no problem with the above inspection, it will be more troublesome. a sign of mechanical aging or damage and requires servicing.
