Kohler diesel engine KDI innovation more advanced
1. Fuel common rail system
Kohler used the most advanced on the market common rail system, specifically for the harsh working conditions, industrial and construction with excellent durability and engine design. High pressure oil pump and advanced multiple injection control system (control injector), the air-fuel ratio in the injection process to achieve the best.
2. Turbocharger and booster air cooler
The specially tuned exhaust turbocharger reduces the turbo lag response and provides accurate air volume, thus optimizing the low speed torque performance of the engine. The special design of the lubricating system, ensure the durability of the extension of the turbocharger. Use a pressurized air cooler to ensure proper intake temperature to achieve the best engine performance and meet emission standards.
3 and 4 valves
The design of four valves per cylinder enables the nozzle to be installed more accurately on the centerline of the cylinder shaft and is located in the center of the combustion chamber. This design allows the fuel to be atomized and distributed symmetrically in the combustion chamber to ensure optimum mixing of fuel and air. The combustion chamber and inlet shape were designed by CFD analysis to optimize the combustion process.
4, ECU
The engine electronic control unit (ECU) and common rail injection system have become part of the most advanced vehicle engine management system, especially for industrial equipment and construction machinery. It controls engine standard parameters in all directions to obtain engine performance and meet emission standards. In the final application, the ECU can be connected to other electronic systems through the CAN data interface to optimize the engine operating parameters. ECU specific function options, provide different speed regulation characteristics for OEM, to ensure the overall compatibility of the device.
5, EGR system
Exhaust gas in circulation (EGR) system is a new design through CFD analysis and comprehensive research. The final design of the EGR system is to apply for a patent. The most common failure of EGR system is the valve block problem, and the "high temperature" EGR design will avoid this problem. The exhaust passes through the cylinder head, which is conducive to the initial cooling of the exhaust before entering the EGR valve, thereby reducing the overall size of the engine.
