Chongqing Sanchai Power Group, the predecessor is Chongqing Sanchai Engine Manufacture Co., Ltd. Established in 2009, located in Tongliang Industrial Park of Chongqing, mainly specialized in research, development, design, manufacture, sales and after-sale service of diesel engines, gas engine, marine engines and engine spare parts. Sanchai's prime products include newly developed series of high-power engines (from 132.6 to 2000 HP), such as NT855, KTA19, KTA38, and KTA50 series diesel engine. Suitable for generator sets, engineering machineries, marine/vessels and heavy duty truck field.
Diesel Engine Technology
To operate effectively and safely, the engine must continuously deliver air, fuel and lubrication to the cylinders. In addition, engine emissions, created as by-products of combustion, must be treated to meet global environmental standards.
While an engine can breathe in and operate on surrounding air collected through intake valves, it’s not ideal. Oxygen density changes depending on air temperature and altitude.
A turbocharger compresses intake air to optimize combustion efficiency. Spinning the compressor is done through the force of exhaust gases coming out of the cylinders. These gases spin a turbine, which then spins the compressor wheel on the other side, sending compressed fresh air to the intake valves.
As with air and exhaust valves, Sanchai fuel systems use the camshaft to control the injection process. The amount of fuel delivered to the cylinder is controlled in part by the speed at which the engine turns, since the camshaft is connected to the crankshaft.
The injection system must atomize fuel for it to combust, so the spray nozzles have either a single hole near the tip or a series of holes around the side.
Almost all modern diesels use a high-pressure common rail system, in which fuel is supplied to a common tube, or “rail,” by a pump to keep fuel available to the injectors when needed. These injectors work with extreme pressures and an electronically controlled injection system.
All these moving parts create substantial friction. Without proper lubrication, severe damage would result. A sump pan under the crankshaft, lube pump and various drillings in the block supply lubricating oil to friction surfaces throughout the engine. This oil reduces wear and suspends microscopic particles from the engine and the combustion process to prevent them from damaging the engine.
To offset the heat produced by friction and combustions in the engine, coolant is pumped throughout tubes and passages in the block, flowing around the sides of the cylinder walls and liner. Heat in the coolant is then dissipated through the radiator.
