What is the difference between 1.5L and 1.5T cars?
1 Answers
1.5L and 1.5T cars differ in the following aspects: 1. Different working principles: (1) A 1.5L naturally aspirated car relies on negative pressure in the cylinder to intake air, and the concentration of air drawn into the cylinder is normal. (2) A 1.5T car derives the kinetic energy of its turbocharger from the exhaust gases, hence the turbo is also known as an exhaust gas turbo. The exhaust gases expelled by the engine impact the turbine, driving the impeller on the other side to compress air, which is then sent into the engine. This results in more complete combustion of the fuel in the engine, delivering stronger power. 2. Different fuel consumption: (1) The 1.5T consumes more fuel because the turbocharger compresses more air into the cylinder, and the engine's electronic fuel injection system adjusts the fuel injection volume based on the air intake, increasing fuel injection as air intake rises. (2) The 1.5L consumes less fuel. 3. Different prices: Due to the additional turbocharger in the 1.5T engine, 1.5T cars are more expensive. 4. Different levels of development maturity: Naturally aspirated engines are the earliest type of engines, while turbocharging adds a turbocharger to the naturally aspirated engine. Naturally aspirated cars have more mature technology, and naturally aspirated engines offer greater reliability.
