Body type Gantry engine without cylinder liner design The body of the engine without Gantry type cylinder liner design improves the structural strength of the engine block and make a compact and lightweight structure. Integrated exhaust manifold design and heat exchanger The integrated design of the exhaust manifold heat exchanger and exhaust manifold placed in a cavity surrounded by water. Outside water circulation reduces the temperature of the exhaust gas. The cooling effect is better and the noise is lower. The heat exchanger tank replaces a radiator and cooling fan to the more compact structure. Four valves per cylinder design Two inputs and two exhaust valves improve intake, performance exhaust and efficiency. the injector is installed on the center line of the cylinder to the fuel injection pulses, even with a swirl pattern to eliminate uneven optimal aerosol.
