Control emissions at the cylinder level, with Zero CO, Zero HC and near zero NO
This ratio is about 3.5 in a small fast vehicle, while it is about 7 in a slow heavy commercial vehicle.
This extra length of the connecting rod, needed to secure higher torque force, can be given up, by lending a higher torque requirement to a turbo charge method, available by the way of having a power stroke and compression performed simultaneously.
Another solution is to create another positive method for the heavy slow movement of a commercial vehicle engine, where every stroke is a power stroke in our Relative-Motion Engine, where our 2000 RPMs is equivalent to a Conventional Engine doing 4000 RPMs. This fact allows us to design higher speed engines with inherent safety before reaching allowed higher rotation limits.
Thermal efficiency enhances at lower piston speed, due to decreased friction, is guaranteed when every stroke is a power stroke in our four stroke engine.
also when every stroke is a power stroke, certain power output requirements can be achieved at half the piston RPM, and that will double the available air flow per cycle, causing an elevation in the torque curve which is proportionate with thermal efficiency and air flow per cycle,
The Air flow per cycle, is also depends of turbo charge boost, which is not only can be utilized at over 70% energy recovery rate of efficiency at our relative motion design, compared with 25% efficiency in conventional engine, but also turbo charge in the relative motion method, can be applied during the time span of the power stroke, while in conventional engines, it can only change the pre combustion conditions.
For all that, a heavy vehicle can now be more robust in ( more work) at a more robust motion.
Known challenges with commercial vehicles is the need for bigger number and bigger size of working cylinders, needed to meet the higher loads requirements.
Trends in developing modern engines, tend to down size cylinders and to minimize piston average speeds, along with supercharging the engine.
Our Relative Motion engine allows turbocharging/supercharging during the time span of the power stroke, rather than pre-stroke, which can allow the use of much smaller engines without sacrificing torque capabilities.
A power stroke every cycle means we can also operate at half the conventional piston speeds, to achieve less friction and less heat production along with minimizing the cooling requirements.
Relative-Motion solution is also mainly beneficial for solving diesel challenges of exhaust emission. Diesel engine noise is decreased by minimizing stroke initial force by more than three folds.
