Q: Why a lot of sports car engine is rear?: To the market only RR car Porsche 911, for example, the official announcement of the car before and after the weight ratio is 39:61, almost equal to a reverse of the FF car, and MR car weight ratio is more uniform, Porsche Boxster 46: 54, Ferrari 360 Modena is 43:57. Although some depots appreciate the FR car can do 50:50 car weight ratio, control is also more handy, but from the accelerated point of view, or the first light weight of the MR and RR the most favorable, for the weight ratio before and after Possibly small, the sports car will use the head narrow tail width of the body design and the use of relatively thick rear wheels.

Q: Does the car use engine brakes to increase fuel consumption?: 2, the use of engine brake is to lift the accelerator pedal, but do not step off the clutch, the use of the engine compression stroke compression resistance, internal friction and intake and exhaust resistance to the drive wheel to form a braking effect.

Q: What are the systems in the car engines?: Including five systems and two institutions of gasoline engines, the five systems are: ignition system, starting system, lubrication system, cooling system, fuel supply system, two major institutions are: crank and connecting rod mechanism, gas distribution mechanism

Q: What's the difference between the engine 1.8T and the 1.8L?: It is to use the engine emissions as the power to drive the turbine room of the turbine (located in the exhaust tract), turbine driven by another coaxial impeller in inlet, impeller compresses the air filter from the pipeline delivered fresh air, then into the cylinder

Q: What does the MAP diagram of an engine mean?: The ignition curve control chart for engine under various working conditions, said a series of sensors through to the MAP map, such as engine speed sensor, intake manifold vacuum sensor (engine load sensor), solar term door position sensor, crankshaft position sensor to determine the engine working condition, find out the required ignition engine condition here the advance in the MAP chart, according to the requirement of ignition

Q: The difference between a car engine and an engine: Someone called the engine engine, in fact, the engine power output is a set of equipment, including gear, engine and transmission shafts, visible engine is only one part of the engine, but the core part is the engine, so the engine is called the engine too.

Q: What are the two major structures of an engine?: 1. crank connecting rod crank connecting rod mechanism includes piston, connecting rod and crank with flywheel. This is the mechanism whereby the engine generates power and turns the reciprocating linear motion of the piston into the rotational motion of the crankshaft. In structural analysis, the body block and the crank link mechanism are often combined together. 2. the valve train includes the intake valve, the exhaust valve, the tappet, the intake camshaft, the exhaust camshaft and the camshaft timing belt (driven by the crankshaft timing gear). The function of the valve train is to charge the combustible gas into the cylinder in time and exhaust the exhausted gas from the cylinder in time.

Q: Why some engine exhaust pipe in front, some are in the back! What are the advantages and disadvantages: Which for many riders may be a relatively vague words, but in fact it has been very wide in our side, and open the hood to see, maybe your car is using the anti-engine!

Q: What is the power of the engine?: Its exact definition is: the piston in the cylinder in the reciprocating movement, reciprocating a certain work, its unit is Newton.

Q: What is a turbocharged engine?: First, the intake of the turbine chamber is connected to the exhaust manifold of the engine, and the exhaust port is attached to the exhaust pipe. Then the intake port of the supercharger is connected to the air cleaner duct and the exhaust port is attached to the intake manifold,
