The SYZ series diesel engine is a new product independently developed by Shangyan Power. It integrates advanced technologies from home and abroad and carries out a series of technological innovations. It includes four-valve, low-vortex air passage, oil and gas balance, efficient cooling, light weight, and high integration. , can be electronically controlled upgrades and other technologies, designed to take into account the high-strength program, the maximum burst pressure can reach 18MPa. With the same displacement, this model has achieved a 15% increase in power over other products, a small volume of 18%, and a lighter weight of 16%. It provides users with a new generation of high-quality engine products that are reliable, fuel-efficient, low-cost, and meet emission requirements.




It is particularly suitable for use as a main driving force on fiberglass ships such as fast boats and yachts where space is limited.



Increase the intake air and greatly increase the diesel power
Including four valves, increase the intake air, easy to meet emission requirements, increase power.
Low vortex air passage: Both inlets use a relatively small eddy current ratio to reduce intake eddy current losses and increase the intake charge factor.


Reduce fuel consumption
Oil and gas balance: The balance chamber is designed in the body to reduce pumping losses and reduce fuel consumption.
Efficient cooling: The tangential inlet waterway design reduces the cooling area of the water jacket in the cylinder liner and increases the flow rate of the cooling water, thereby reducing the cooling power consumption.


Low cost, design
Lightweight: High-strength materials are used to maximize power while still ensuring engine reliability.
Highly integrated: reduce appearance pipe connection design, reduce three leaks, enhance the appearance of beauty.
