Why CHM

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

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.
