Why CHM-MOTORS
We made the first opposite piston engine with no camshaft that reduces 65% of the losses associated with lateral movements and cylinder head resistance.
Our revolutionary Opposed Piston Rotary Engine (OPRE) design has 4 distinct advantages:
LOW RESISTANCE
ENGINE CYCLE
ENGINE SIZE
ENVIRONMENTAL FRIENDLY
Low head resistance
means
Cooler engine
means
Higher RPM
means
More power
for less fuel
Less parts
(No crankshaft ,Engine head, Camshaft, Timing belt, valves)
means
Small, lightweight engine means
Easy to maintain and manufacture
means
More reliable engine
180 engine cycle
means
Maximum
cycle utilization
means
More power
for less fuel
Energy saving
Opposed Piston
Rotary Engine
means
More power
for 40% less fuel
means
Emit 70% less CO2
(TIER3 / EURO6)
In conclusion, our new OPR engine is Lightweight (1/5 of a regular engine), compact size with minimal Parts (cheaper to maintain and manufacture), Powerful (Weight: HP Ratio – 0.3), Efficient (Consumes 40% less fuel), Environmental friendly (Emit 70% less CO2)
and can run on any different fuel (including gasoline, diesel, gas and ethanol).
OUR WORK
All our blueprints and calculations are done and we hold 3 patents in 20 countries including China.
Cooling system
The OPR engine’s oil cooling system is based on cooling the pistons by an oil circulation system which lubricates the bearings and rotor as well.
Intake and exhaust
OPRE is a two-stroke engine with two pistons in one cylinder, moving in opposite directions, to form the combustion chamber, the pistons cycle, opens and close the intake and exhaust ports in an un synchronize timing, to manage the gas exchange process.
Conversion of motion
OPR engine employs a new design converting a linear reciprocating piston stroke to rotary motion by using an elliptically shaped rotor.
We believe our engine can compete in the Car, Drones, Generators and Compressors sector
Compressors
X2 more effective
Generators
Weights 1/7 of modern generator
Drones
x2 longer flight time
Cars
Stronger and more efficient
ABOUT US
CHM Motors is an Israeli based private company established in 2009. The company is comprised of engineers which specializes in mechanical, design, electronics and software.
we looked at today’s combustion engine and were appalled with its inherent inefficiencies... we knew we could do better!
and we did :)
We completely reimagined the traditional combustion engine with our new revolutionary ORPE design that eliminated the need for a camshaft, there for significantly reducing 65% of the losses associated with lateral movements and cylinder head resistance.
Our goal is to defy industry’s conventions and make our engine smaller, stronger, cheaper, fuel efficient and green.
PROTOTYPE
We have a working prototype that successfully passed the cold and hot run stages.
