Gasoline engine is an engine fueled by gasoline.

BMW, Honda, Toyota, Mercedes-Benz and Volkswagen have the best engines;Mercedes-Benz has the highest price-performance ratio. Although its price used to be relatively high, its strength is indeed very strong. The current price is relatively affordable, but the configuration is as good as before, so I think Mercedes-Benz's performance ratio is stronger.

First place: Honda. The engine failure rate of imported Honda cars is 0.29%, which can be said to be very high. The most famous masterpieces of the engine of Japanese Honda cars are the VTEC system and the i-VTEC system, which have high performance.

BMW's N54 is Europe's 2JZ, a famous generation. The origin of the N54. At the beginning, BMW's engine performance was not outstanding (it was still excellent on civil engines), but there is a saying that it did not progress or retreated. Yes, at that time, Japanese car brands Lexus and Nissan worked hard to develop 2GRFSE series and VQ series engines.

v engine is a high-performance engine, which is characterized by a larger number of valves, smoother intake and exhaust, and can provide greater power output. Therefore, many car brands have adopted 16v engines. Let's take a look at which brands of 16v engines are better.

Engine performance index-dynamic index

Generally, the effective torque, power, speed and average effective pressure of the engine are used as indicators to evaluate engine performance. Effective torque: The torque output by the engine is called the effective torque, which is written as Te, and the unit is Nm. The product of the effective torque and the crankshaft angular displacement is the effective force of the engine output.

The main indicators of engine performance are: speed, power, torque, fuel consumption rate, etc. These indicators are usually marked in the instructions of the car or engine. In addition, there are some relative indicators, such as power increase, torque increase, mass increase, mass ratio, etc., which can be compared between different engines.

The three performance indicators of the engine include the dynamic indexStandard, economic indicators and environmental indicators, dynamic indicators refer to the size of the functional force of the engine, economic indicators refer to the expression of the effective fuel consumption rate, and environmental indicators are the exhaust quality of the engine.
