What kind of engine is Changan Yidong?

Changan Yidong is equipped with 1.6L naturally aspirated and 1.5T turbocharged direct injection engines.

Natural inhalation (English: Normally inhalation) is a kind of automobile air intake, which is a form of atmospheric pressure forcing air into the combustion chamber without any supercharger.

Turbine direct injection (TD) is a diesel engine. Turbo-direct-injection supercharged engine directly injects fuel into the cylinder through a high-pressure injector. Because the top of the piston is designed as a concave bowl, the fuel will form a spiral mixture in the cylinder.

EADO is a global strategic vehicle with international level, which was carefully built by Changan Automobile's global R&D team for three years. It is a global full-time advanced mid-level car. 20 12 On March 27th, Changan Automobile, a self-owned brand, announced the official launch of its brand-new car EADO Yidong.

Working principle of naturally aspirated engine

Naturally aspirated type has no supercharger, that is to say, air simply passes through the air filter-throttle valve (commonly known as "throttle valve")-intake manifold to reach the "cylinder", and gasoline is directly injected into the intake manifold through the fuel injector.

Take a four-cylinder engine as an example, the piston does work with four strokes: downward (the intake valve is open, there is a pressure difference, and the mixture of air and fuel enters the cylinder under the action of the pressure difference)-upward (the intake valve is closed, the mixture is compressed, and the piston is ignited when it reaches the highest point)-downward (the mixture burns and expands, pushing the piston to do work and output power)-upward (the exhaust valve is opened, and the piston is exhausted).

Natural inhalation refers to inhaling the mixed gas by using the naturally formed pressure difference in the first stroke above. Pressurization refers to compressing the gas first, increasing the pressure and density of the gas, opening the valve, increasing the intake volume by using the pressure difference and the high pressure of the gas itself, and improving the power.
