5 kinds of engine technology, less oil problems

The engine is one of the most important parts of the car and plays a vital role in the entire car. Many people who buy a car like to see which engine is equipped, and they buy a car with a good engine, not only Can save a lot of oil money, even if it is to repair the car can also be avoided, this is mainly some good engine, high reliability and stability, good fuel economy reasons! Today Xiao Bian recommend 5 engines to everyone, buy a car look for them, buy it without loss or regret!

1, Honda VTEC

When it comes to Honda's engine, it may be that many people will talk about the earth dream. Earth dream is Honda's main technology for many years to come. Actually, Earth Dream is just a name. The main technology of Honda's engine is VTEC. This is a fact that Honda's housekeeping technology will not change. The engine of the Earth Dream is also based on VTEC. Just adding direct injection and improved inlets reduced fuel consumption and increased power. After all, Earth Dreams is still VTEC. Honda's engines are famous all over the world. Buying a car is not a blow!

2, Toyota THS

Many old drivers know that the stalks are not bad, Toyota is not bad, and the poor are repaired. Toyota's engine technology is also quite powerful. Toyota has only 1 car in 171 cars that can cause engine defects. The Toyota V6 self-ignition and intake engine on the Reitz and Crown vehicles is arguably the pinnacle of Toyota's engine! The “Dynamic Force Engin” in-line four-cylinder 2.5L direct injection engine, which is the main force in the future, adopts a high-speed combustion and variable control system to reduce exhaust, cooling and mechanical operation energy losses. Its fuel and HEV plates have a thermal efficiency of up to 40%. 41%.

3, Nissan VC-Turbo

Nissan truly achieved a variable compression ratio on this VC-Turbo 2.0T engine, adding a set of mechanisms for the eccentric and crank connecting rods, in order to change the top dead center and bottom dead center position of the piston during operation, The engine's compression ratio can be freely adjusted from 14:1 to 8:1. When the vehicle is engaged in high-speed cruising and other fuel economy-oriented operating conditions, the engine can ensure a higher compression ratio to improve fuel efficiency; and when the vehicle needs to accelerate the overtaking, the engine can reduce the compression ratio to a certain extent, in order to pursue more Strong power output. Double-cycle + variable compression ratio, the combination of these two technologies, its utilization of fuel is absolutely unmatched by traditional engines.

4, Mazda Chuang Chi blue sky

Chuang Chi blue sky is not just for the engine, but for the transmission, chassis and body structure optimization technology. Chuangchi Blue Sky Gasoline Engine actually has two cycle modes: Otto Cycle and Miller Cycle. The Otto cycle is a cycle mode in which the compression ratio is equal to the expansion ratio, and the Miller cycle is a mode in which the compression ratio is smaller than the expansion ratio. Under high load conditions, the engine is an Otto cycle, while under the remaining conditions the engine is a Miller cycle.

5, the public EA888

The engine has a great balance of potential and has great potential. It is a powerful engine in the family car, and in the field of retrofitting, it is the climax of people in the conversion zone. Gives people the impression of being very tolerant, this is often imitated, but the engine has never been exceeded, has developed to the third generation, and even the public has withdrawn from the fourth generation of EA888 engine before the third generation of B-type machine Type, with a high compression ratio of 11.7:1, and an exhaust variable valve generation system!
