What is a compression ignition engine
A compression ignition engine is an engine that does not require a spark plug for ignition. This engine relies on high temperature and pressure at the end of the compression stroke to ignite the combustible mixture. Diesel engines are compression ignition engines. Among gasoline engines, only Mazda uses a compression ignition engine.
Mazda Angkor Sierra uses a 2.0 supercharged internal combustion engine.
The Mazda Envision Sierra is a compact car. Its length, width and height are 4662 mm, 1797 mm and 1445 mm respectively, and the wheelbase is 2726 mm.
Ancyra's 2.0 boost internal combustion engine has a maximum power of 132kw and a maximum torque of 230 Nm. The maximum power of this engine is 6000 rpm and the maximum torque is 4000 rpm.
This engine is equipped with a 24v mild hybrid system and in-cylinder direct injection technology, and uses an aluminum alloy cylinder head and cylinder block.
Using aluminum alloy cylinder heads and blocks can reduce the weight of the engine, thereby improving the vehicle's fuel economy and handling.
This engine is matched with a 6at gearbox.
Using a 6at gearbox can improve the car's fuel economy and shift smoothness.
Moreover, the reliability and durability of the 6at gearbox are also good.
Arcella's front suspension adopts MacPherson independent suspension, and the rear suspension adopts torsion beam non-independent suspension.
Torsion beams are used in the rear suspension to expand rear passenger and trunk space.
What is the difference between Mazda compression ignition engine and ordinary engine?
The difference between Mazda compression ignition engine and ordinary engine:
1. Different maximum powers
1. The maximum power of the 1.6 engine is 79kW, the maximum horsepower is 107Ps, and the maximum power speed is 6000rpm;
2. The maximum power of the 2.0 engine is 108kW, the maximum horsepower is 150Ps, and the maximum power speed is 6500rpm.
2. Different maximum torques
1. The maximum torque of the 1.6 engine is 145N.m, and the maximum torque speed is 4000rpm;
2. The maximum torque of the 2.0 engine is 182N.m, and the maximum torque speed is 4500rpm.
3. Different matching gearboxes
1. The transmission matched with the 1.6 engine is a 5-speed manual transmission or a 4-speed automatic manual transmission;
2. The transmission matched with the 2.0 engine is a 6-speed manual transmission or a 5-speed automated manual transmission.

What are the characteristics of a compression ignition engine?
What does a compression ignition engine mean? What does a compression ignition engine mean? Compression ignition engine A compression ignition engine is an internal combustion engine that does not rely on electric sparks for ignition, but relies on the high temperature of the gas at the end of compression to cause the mixture to ignite. A diesel engine is a compression ignition engine. ?@2019
Advantages and disadvantages of compression ignition and ignition
Regarding the difference between compression ignition engines and ignition engines:
1. The engine fuels are different. In fact, compression ignition engine fuel can usually only be diesel, and it is difficult to achieve compression ignition with gasoline. The ignition engine fuel is usually gasoline.
2. Not required for compression ignition engines Ignition system, a spark-ignition engine requires an ignition system.
3. The engine compression ratios are different. Compression ignition engines often have a higher compression ratio than spark-ignition engines.
About the advantages of Mazda compression ignition engine:
Mazda has realized the world's first mass-produced compression ignition technology gasoline engine, which can take into account the advantages of ignition and compression ignition engines. Mazda's original new SPCCI spark ignition controlled compression ignition technology draws on the technical essence of gasoline engines and diesel engines to provide more powerful power output and more responsive response during starting and acceleration. At the same time, it maintains its technical advantages in power ductility, heating performance and environmental protection efficiency, saving more fuel and making emissions cleaner.
About the disadvantages of Mazda compression ignition engine:
The theoretical and technical exploration of Mazda’s compression ignition engine is more significant than its actual use. The spirit is commendable, but the current market advantage is not obvious. Similar to rotary engine. As the world's first mass-produced compression-ignition ignition technology gasoline engine, its research and development costs are high, resulting in high prices and extremely low cost performance at the terminal sales level.
The above is all about the compression ignition engine, what is a compression ignition engine, and the related content of yara. I hope it can help you.
