ENGINE introduce

The engine assembly, also known as the engine, is a machine that can convert one form of energy into another more useful form of energy, usually converting chemical energy into mechanical energy The electric motor, which converts electrical energy into machine energy, is sometimes applicable to both power generation devices and the entire machine including power devices. For example, gasoline engines, aviation engines, and automotive engines generally obtain kinetic energy through internal combustion of gasoline (diesel), so automotive engines are internal combustion engines. According to the different fuels used, they can be divided into gasoline engines and diesel engines. Gasoline engines and diesel engines have their own characteristics; Gasoline engines have high rotational speed, low quality, low noise, easy starting, and low manufacturing costs; Diesel engines have a high compression ratio, high thermal efficiency, and much better emission and economic performance than gasoline engines. Secondly, according to the piston motion mode, piston type internal combustion engines can be divided into two types: reciprocating piston type and rotary piston type. The former piston moves back and forth in a straight line in the cylinder, while the latter piston rotates in the cylinder. Thirdly, according to the number of cylinders, it can be divided into single cylinder engines and multi cylinder engines. Engines with only one cylinder are called single cylinder engines; An engine with two or more cylinders is called a multi cylinder engine. Modern car engines often use three cylinder, four cylinder, six cylinder, and eight cylinder engines. According to the arrangement of cylinders, they can be divided into single row, double row, and three row engines. The cylinders of a single row engine are arranged in a row, usually vertically, but sometimes they are arranged in a tilted or even horizontal position to reduce height. A double row engine arranges the cylinders in two rows, The angle between two columns)

What does the engine assembly include

The engine assembly includes a cylinder block, flywheel housing, transmission gear compartment, water pump, fan, transmission mechanism, timing gear, intermediate gear, filter, oil pan, oil pump, V-belt, crankshaft, connecting rod, piston, flywheel, etc

Toyota Yaris L introduce

The Toyota Yaris L, with a body length of 4115mm and a wheelbase of 2550, gives it a significant advantage in space and other aspects compared to competing models such as Honda Fit, Volkswagen Polo, and Ford Fiesta. This car has two powertrain options and six configuration models are available in China, The guide price ranges from 69800 to 108800 yuan. The Zhixuan does not have many configurations specifically designed to improve comfort. The seat positions of all models are manually adjusted. This sporty version of the model uses fabric seats, which are very sporty and wrap around the body well. However, the seat softness is not high, and sitting for a long time may be uncomfortable. In idle mode, the Zhixuan appears very quiet, but when the speed reaches a certain value, the noise becomes very obvious, At speeds of 60km/h and 80km/h, the noise levels are 59.8 and 62.3 decibels, respectively. At this time, most of the noise comes from the engine and wind noise, and there is no sense of the noise caused by resonance of certain components inside the car
