CSRV System Advantages...
Comparative Analysis
Emissions tests conducted by an independent EPA-Compliant laboratory in USA have confirmed the superiority of Coates International CSRV engines in producing significantly lower pollutant. The following chart presents the emission results as reported by an independent laboratory which tested two vehicles, one running with stock engine and the second with stock engine retrofitted with Coates CSRV system.
Both vehicles were tested in steady state with the following parameters:
• No EGR system
•Warm up run on Dynamometer: 30 minutes
•Engine temperature: 180 degrees F
•Inertia Load: 2,000 pounds
•Road horsepower: 13
•Two catalytic converters installed
Emission Type Stock Engine CSRV Engine Improvement
HC (PPM) 36 11.95 66%
CO (PPM) 10 6.10 39%
NOX (PPM) 118 3.30 97%
CO2 (%) 1.59 1.07 32%
Each vehicle was tested under various RPM and MPH scenarios and the above data represent the best results from the multiple test runs.
Engine Dynamics
The average poppet valve opens a maximum of approximately 8 millimeters, restricting air flow. In addition, valves in high compression engines cannot open before top dead center. If they do, they will make contact with the piston and engine destruction occurs. The Coates Spherical Rotary Valve System can open before top dead center and, in fact, can open at any desired point. This flexibility in breathing ports far exceeds the four poppet valve per cylinder combustion engine and allows the engine to run more effectively.
