H Series Diesel Engine

SDEC's new H series engine is an energy-saving and environment-friendly engine professionally made by introducing a design concept from Europe and America, combining advanced four-valve technology, cracking connecting rod, lightweight manufacturing process, etc. It completely meets the National IV and the future National V Emission Standard. This engine fully integrates today's worldwide cutting-edge technologies of internal-combustion engines with such advantages as fuel efficiency, strong power, good reliability and low noise, making it the ideal power for large and medium size passenger cars.

Technology adopted: four valves per cylinder and the fuel injector is arranged vertically right in the center;
Function: increased inlet airflow and better rationalize atomized fuel distribution;
Advantage: improved engine power (horsepower and torque) and decreased engine fuel consumption.

Technology adopted: Nippon Denso's latest generation of HP3 high-pressure common rail fuel system;
Function: maximum fuel-injection pressure reaches 1800bar, the effect of fuel atomization is better, and the flow deviation of the fuel injector is controllable;
Advantage: lower engine emission, noise and fuel consumption.

Applied technologies: modular integration design integrating the engine oil cooler chamber, water pump volute casing, engine-oil pump chamber, etc. on the engine body;
Function: decreased number of engine parts and sealing surface; Advantage; improved reliability.

Applied technologies: integral cylinder cover;
Function: good rigidity of the whole engine;
Advantage: lower vibration and noise.

Applied technologies: patented design of engine body with strengthening rib, high stiffness and high strength;
Function: good rigidity of the whole engine;
Advantage: lower vibration and noise.

Applied technologies: cracking connecting rod;
Function: one-to-one matching of upper and lower covers for connecting rod, preventing mistake and with good alignment;
Advantage: easy repair and maintenance.

Applied technologies: dry-type cylinder liner;
Function: the cylinder sleeve material performs better than the engine body material;
Advantage: improved wearing resistance capacity; repair and maintenance easier than that without cylinder sleeve.

Applied technologies: piston with all-aluminum wavy inner-cooling oil passage;
Function: improved cooling effect of the piston;
Advantage: improved operation reliability of the piston.

Applied technologies: Nippon Denso's world-leading ceramic chip ECU;
Function: small heat dissipation amount requires no external connection of cooling pipeline;
Advantage: high reliability of the entire engine.

Applied technologies: Japanese double-layer material used in the high-pressure oil pipe;
Function: higher pressure-proof and corrosion-resistant capacity;
Advantage: high reliability of the fuel pipeline.

Applied technologies: standardized design of peripheral accessories;
Function: exchangeable with mainstream accessories;
Advantage: easy repair and maintenance.
