Our CY4102 series are inline, water cooled, four-stroke vertical diesel engines.
CY4102BQ Series
1. Performance
By taking advantage of the design philosophy for Japanese ISUZU 4BD1 vehicle engines, we have successfully developed CY4102BQ series high speed diesel engines which have high power performance and are fuel economy.
2. Application
CY4102BQ series diesel engines are ideal for 2-3ton light duty vehicles, 6-7m buses, tourist buses and intercity buses, as well.
3. Optional equipment
Optional devices like air brake, oil brake, air compressor, warm air heater and power steering pump, etc. are available for CY4102BQ series diesel engines, upon customer's request.
CY4102BZLQ Series
1. Performance
CY4102BZLQ series turbocharged intercooled diesel engines are Euro II engines designed and developed based on CY4102BZQ series.
We design and manufacture CY4102BZLQ series of diesel engine by using air to air intercooling technology and we also upgrade the engine's intake and exhaust system, fuel supply system, combustion system, cooling system and lubricating system, etc.
Engine bench test, reliability test, and users' feedback have proved that our CY4102BZLQ series vehicle engines have rational structure, high performance and high reliability. Meanwhile, the cylinder block, crankshaft and piston as well some other key components are made with new structures and new technologies, which greatly enhance the strength and rigidity of our diesel engines.
2. Emission standard
CY4102BZLQ series are Euro II engines.
