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

SUBARU BRZ introduce

The Subaru BRZ was officially released in 2015, with a more sporty exterior design and equipped with 225/40 ZR18 Michelin Pilot Super Sport series tires. The chassis has been strengthened, and the power continues to be equipped with a 2.0L naturally aspirated direct injection engine. The Subaru BRZ tS STI model is currently only sold in Japan, with a limited quantity of 300 units [1] Subaru unveiled the 22 seater new two door hardtop sports car BRZ at the Frankfurt International Auto Show, which opened on September 15, 2011. The new car showcases Subaru's latest research and development achievements, as well as the new generation design concept, pointing the way for future Subaru new cars. The new BRZ is a collaborative development between Subaru and Toyota, and is a sister car of the Toyota 86 (note: the North American version is called the Scion FR-S, the European version is called the GT86, and the Japanese version is called the 86), The car adopts a horizontally opposed engine and front rear wheel drive layout. The suspension forms are front MacPherson independent suspension and rear double wishbone suspension. The wheelbase reaches 2570mm, the car is 4239mm long, 1775mm wide, and 1285mm high
