Eliminating throttling losses must be the first step to seriously improve efficiency. All spark-ignited engines are controlled by suffocation. A simple work-around is a variable area Venturi manifold. www.prvperformance.com

The target emissions can only be achieved by addressing the main constituent of engine efficiency loss -- the pumping loss of the engine. In day-to-day driving 20% of fuel is wasted moving air/fuel in and out of the engine. The throttle plate is a very effective means of controlling the engine. In fact, the throttle plate is as effective as it is inefficient. Engine control via suffocation cannot survive. James Meyer PRV Performance jmeyer@prvperformance.com 303-887-2032

My humble assessment is that the cost from biomass to methanol is the deciding factor for economic viability. Today, the cost of methanol is $1.32 per gallon. Downstream of methanol, everything is a license. Can Sundrop beat the spot price of methanex? Best, James Meyer, MBA/PE (Chemical Engineer) jmeyer@prvperformance.com 303-887-2032

Fuel injector issues are overcome by injecting fuel into the throat of a variable area Venturi. The high air velocity and low pressure at the throat nebulizes and vaporizes the fuel. Concurrently, throttling losses are reduced because the air flow in unrestricted until sonic velocity is reached, at the thoat, near the bottom dead center of the piston cycle.

An effective way to improve the performance of ethanol-fueled engines is to cool the charge with an effective premixing intake manifold. The higher latency of vaporization relative to gasoline provides additional cooling to the charge and therefore improves the torque of the engine substantially. James Meyer Founder, PRV Performance

The entire front end of the process shuts down every night. Consequently, the entire syngas train is in recycle mode most of the time. The intermediate product is mostly methanol, costing $1 per gallon made from natural gas. The economic viability is therefore questionable unless the process is government subsidized.
