1. Knock will suddenly produce shock waves in the cylinder, impacting on all sides, causing strong vibration of the engine's piston, cylinder wall, connecting rod, crankshaft, etc., and irregular metal percussive sound;   2. The temperature of the cooling system is too high;   3. Incomplete fuel combustion and black smoke in the exhaust gas;   4. The engine power drops and fuel consumption increases.   Solution:   1. Reduce the ignition advance angle;   2. Use gasoline with a brand (octane number) in compliance with the regulations;   3. Remove carbon deposits in the combustion chamber;   4. If knocking occurs when the car is going uphill, switch to a low gear in time;   5. When the car starts, don't switch to the direct gear too early.   6. When knocking occurs due to excessive engine load, closing the throttle valve can also reduce knocking.

The engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually the process of working cycle. In simple terms, it burns the fuel in the cylinder to generate kinetic energy to drive the reciprocating movement of the piston in the engine cylinder. The connecting rod connected to the piston and the crank connected to the connecting rod make a reciprocating circular motion around the center of the crankshaft to output power.   The working process of a four-stroke gasoline engine is a complex process, which consists of four strokes (strokes): intake, compression, combustion expansion, and exhaust.   Intake stroke   At this time, the piston is driven by the crankshaft to move from top dead center to bottom top dead center. At the same time, the intake valve opens and the exhaust valve closes. When the piston moves from the top dead center to the bottom dead center, the volume above the piston increases, the gas pressure in the cylinder decreases, and a certain degree of vacuum is formed. As the intake valve opens, the cylinder communicates with the intake pipe, and the mixture is sucked into the cylinder. When the piston moves to the bottom dead center, the cylinder is filled with fresh mixed gas and exhaust gas that was not discharged in the previous working cycle.   Compression stroke   The piston moves from bottom dead center to top dead center, and the intake and exhaust valves are closed. The crankshaft is driven to rotate under the action of inertial force such as the flywheel, and the piston is pushed upward through the connecting rod. The gas volume in the cylinder gradually decreases, the gas is compressed, and the pressure and temperature of the mixed gas in the cylinder increase.   Work stroke   At this time, the intake and exhaust valves are closed at the same time, the spark plug is ignited, and the mixed gas is violently burned. The temperature and pressure in the cylinder rise sharply. The high temperature and high pressure gas pushes the piston down and drives the crankshaft to rotate through the connecting rod. In the four strokes of the engine's work, only this stroke can realize the conversion of heat energy into mechanical energy, so this stroke is also called the work stroke.   Exhaust stroke   At this time, the exhaust valve opens, the piston moves from bottom dead center to top dead center, and exhaust gas is discharged from the cylinder as the piston moves upward. Because the exhaust system has resistance and the combustion chamber also occupies a certain volume, it is impossible to exhaust the exhaust gas at the end of the exhaust gas. This part of the remaining exhaust gas is called the residual exhaust gas. The residual exhaust gas not only affects the charging, but also has an adverse effect on the combustion.   At the end of the exhaust stroke, the piston returns to the top dead center. This completes a work cycle. Subsequently, the crankshaft continues to rotate depending on the inertia of the flywheel, and the next cycle begins. After repeating this cycle, the engine keeps running.   

Because gasoline is low in viscosity and evaporates quickly, it can form a uniform mixture with air outside the cylinder, and then suck the mixture into the cylinder, or use a gasoline injection system to inject gasoline into the cylinder to expand the gas and do work. The disadvantages of gasoline engines are lower thermal efficiency than diesel engines, higher parking consumption, more complicated ignition systems than diesel engines, and lower reliability and ease of maintenance than diesel engines.

It is the assembly base of various parts of the engine. It includes cylinder head, cylinder block, lower crankcase (oil pan). The cylinder head and the inner wall of the cylinder block together form a part of the combustion chamber. Many parts of the body are part of other systems. Crank Mechanism It is the mechanism through which the engine generates and transmits power, and it converts the linear reciprocating motion of the piston into the rotational motion of the crankshaft to output power. It includes pistons, piston pins, connecting rods, crankshafts with flywheels, and cylinder blocks. Air Supply Including intake valves, exhaust valves, valve lifters, camshafts and camshaft timing gears (driven by crankshaft timing gears), etc. Its function is to fill the combustible mixture into the cylinder in time and discharge the exhaust gas from the cylinder in time. Fuel supply system Gasoline engine fuel supply system includes gasoline tank, gasoline pump, gasoline filter, air filter, carburetor, intake pipe, exhaust pipe, exhaust muffler, etc. Its function is to mix gasoline and air into a suitable combustible mixture and supply it to the cylinder to prepare for combustion, and to discharge the exhaust gas generated by the combustion out of the engine. cooling system Mainly include water pump, radiator, fan, water distribution pipe and cylinder block and water jacket in the cylinder head. Its function is to dissipate the heat of high-heat parts to the atmosphere to ensure the normal operation of the engine. Lubrication system Including oil pump, pressure limiting valve, lubricating oil duct, filter collector, oil filter and oil radiator, etc. Its function is to supply lubricating oil to the friction parts to reduce the friction resistance between them, reduce the wear of the parts, and partially cool the friction parts and clean the friction surface. Starting system Including the engine's starting mechanism and its accessories. 

Gasoline Engine is an engine that uses gasoline as fuel and converts internal energy into kinetic energy. Because gasoline is low in viscosity and evaporates quickly, gasoline injection system can be used to inject gasoline into the cylinder. After compression reaches a certain temperature and pressure, it is ignited with a spark plug to expand the gas and do work. Gasoline engines are characterized by high speed, simple structure, light weight, low cost, stable operation, and convenient use and maintenance. Gasoline engines are widely used in automobiles, especially small cars.

1. The engine valve drive mechanism adopts a hydraulically supported ball rocker structure. Compared with the hydraulic tappet valve drive mechanism commonly used in general gasoline engines, this novel valve drive mechanism has the advantage of relatively small friction torque, so The required driving force is also small, which can effectively reduce engine power consumption and fuel consumption.   2. In order to effectively reduce the weight of the entire vehicle, the 1.4-liter gasoline engine uses aluminum alloy cylinders, which has achieved a very obvious lightweight effect.   3. The use of special materials and specially processed plastic air intake pipes instead of traditional metal air intake pipes not only achieves a lightweight effect, but also effectively reduces the wall resistance of the air intake pipe, improves air intake efficiency, and increases engine power.   4. The expanded connecting rod processed by advanced technology is used to expand the processed connecting rod large-end hole with special expansion equipment, instead of the original sawing and grinding process. In this way, the zigzag "Huff" surface of the breaker connecting rod can be used to ensure absolutely accurate fastening and positioning, thereby reducing friction and prolonging the service life of the connecting rod.   5. The use of hot-sleeve camshaft, compared with the original camshaft, can not only reduce the weight of the camshaft, but also achieve higher cam profile accuracy and more accurate valve timing.   6. The throttle adopts an electronic control device, also known as E-GAS electronic throttle. This control device can coordinate and reasonably manage the instantaneous requirements of the engine torque and output power of the various operating conditions of the car, such as the driver accelerating, overtaking, and starting the air conditioner. It can make the engine's operating state at each operating point always be in the optimal range, which can not only meet the requirements of low emission and low fuel consumption, but also optimize the driving performance of the whole vehicle.   7. Improving the layout of the engine's intake system can effectively reduce the temperature of the intake air charged into the engine and increase the intake density, so that the engine can output more power on the basis of improved charging efficiency. The specific improvement is to arrange the engine's air intake pipe on the left side of the engine front module above the cooling water tank.   8. In order to improve the anti-corrosion ability of the cooling water tank and prolong the service life of the water tank, the cooling water tank radiating fins arranged in the front module of the engine are all covered with plastic.   9. In order to prevent the bottom of the engine oil pan from colliding and rubbing against uneven roads and damaging the engine, a metal protective plate can be installed under the oil pan.   10. In order to effectively heat insulation, sound insulation and shock isolation, so that it will not be introduced into the passenger compartment and affect the riding comfort, a heat insulation shielding plate is installed in the exhaust pipe of the POLO car. 

Engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Such as internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generating device, but also refers to the entire machine including the power device (such as: gasoline engine, aviation engine). The engine was first born in England, so the concept of engine also originated from English, and its original meaning refers to the kind of "mechanical device that generates power."
