Four Air Valves (two inlet valves + two exhaust valves)

Greatly improved the air flow efficiency and combustion efficiency.
Remarkably reduced emission and fuel consumption.
Common Rail Fuel System Spray Pressure: 160Mpa
Optional Electronic-controlled In Line Fuel Pump spray pressure:90-100MPa
Exhaust Turbocharger

Exhaust turbocharger reduce the fuel consumption and emission.
While air to air intercooler cooling system increase the engine power 3%-5% every 10 degrees dropped of the boosted air.
Air to Air Intercooler Technology

The engine power will increase 3%-5% every 10 degrees dropped of the boosted air.
The NOX emission will greatly decreased.
Engine low speed efficiency greatly improved.
The aluminum ripple features high efficiency of the heat conduction.
The boosted air temp can be cooled to 50-60 degrees.
The intercooler and the turbocharger are perfectly matched in engine to achieve the target cooling temp.

KIPOR six-cylinder diesels feature OHC structure. Thus the air valve tappet and push rod are deleted and the driving system between the cam and air valves is simplified. Resulted the engine structure is more compact and the driving efficiency is greatly improved.
The Engine Control Unit (ECU) is The Key Control Element of The Common Rail Diesel

Kipor has its own unique technology developed after many years of research which ensures an environmentally friendly engine.
Kipor 9L, 14L and 18L series common rail diesel engines utilize Kipor’s own ECU technology.
Strict Quality Control of KIPOR New Generation Engines

Emulation technique is widely applied  to ensure the engine performance since the design phase.
KIPOR invested many advanced testing facilities of engine.
Various strict testing performed to the components and engine itself to ensure the final quality.
Benefits of KIPOR New Generation Engines

Low Fuel Consumption
Lower Operating Costs
Electronic control of the combustion process and high thermal efficiency rating.
Simplified Service and Maintenance Work and Longer Service Intervals

Oil change at 500 hour intervals (normal operating conditions)
Filters grouped for ease of service and maintenance
Easy access to engine installation for service and maintenance
Low Emissions

Reduces nitrogen oxide (NOx)  emissions by over 50%
After treatment system consisting of an Oxidation Catalyst and diesel particulate filter reduces particulate matter emissions by 90%
Maintenance Free Crankcase Breather Separator

Low exhaust emissions meets  current exhaust emission  legislation (US Tier 3/EU Stage IIIA)

Robust structures keep the moving parts running smoothly throughout   the engine life
The latest premium sealing technologies prevent any fluid leaks.
Low Noise (89dba at 1m max) – Makes Your Machine Operator’s Life Easier

A rigid bedplate reduces vibration and noise generation whilst a rear geartrain further reduces noise output
No metal-to-metal contact between engine and covers isolates them, again reducing vibration and noise
Laminar steel oil pan has a cushioning effect to deaden sound.


Engine is the flagship product of KIPOR. Today there are three series engines general-purpose gasoline engine, general-purpose diesel engine and multi-cylinder diesel engine. Those engines are not only equipped to KIPOR generator sets, but also directly sold to global market. Since the future emission standard demands, KIPOR continues the improvement for the fuel and engine structures to reduce the impact on environment. Today, most of KIPOR can meet EPA standard. “Green Engine” is the target of KIPOR.Due to the requirements of climate protection and environmental protection, which have continually increased in recent years, the industry has now intensified the focus of its research and development divisions on making these engines not only more efficient, but also cleaner. Thus, clean air and the preservation of natural resources have become important objectives of our development work. The challenge is to be able to bring competitive products onto the market, while paying particular attention to the technical and economic framework conditions.
