The Fairbanks Morse Model 38 opposed-piston engine was designed and developed for a wide array of electrical power generation and heavy industrial applications. When equipped with Enviro-Design technology, Fairbanks Morse engines utilize pre-combustion chambers to reduce the quantity of pilot diesel fuel required for ignition.
The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. Use of the thermal energy contained in the car’s exhaust gas also offers major saving and comfort potentials. Not every technology is equally sensible for each type of engine, BMW notes.
Achates Power, which is developing a family of two-stroke, compression-ignition (CI) opposed-piston (OP) engines, has designed and is developing a light-duty diesel concept engine, the OP4. liter OM651 Euro 5 engine, said Fabien Redon VP, Technology Development at Achates Power, the OP4 design shows a modeled 13.5% Click to enlarge.
Key changes to implement the integrated cycle are isothermal compression and heat addition from the exhaust gas to the charge air after the end of compression. To transfer exhaust gas heat at the end of compression requires the use of a “split cycle” in which the standard four-stroke sequence is split into two separate elements.
The first system is the innovative recovery of thermal energy by an electric generator powered by exhaust gases. The V-4 gasoline engine of the Porsche 919 Hybrid features direct injection, turbocharging and an energy recovery system for the exhaust gases. Click to enlarge. The 470 hp, 4.0-liter
The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.
The order from Busslink is Scania Sverige’s largest single bus transaction in the Swedish market since 2004. The third-generation ethanol engine is an adaptation of Scania’s 9-liter diesel engine with charge-cooling and exhaust gas recirculation (EGR). Scania’s third-generation CI ethanol engine.
This technology also optimizes phasing on both intake and exhaust camshafts by spinning them ever so slightly to advance or retard valve timing, resulting in improved throttle response at initial throttle tip-in, reduced emissions at part throttle and enhanced efficiency at higher rpm. Gains in new vehicle fleet economy by OEM, 2004-2009.
A significant challenge in designing a diesel reformer is the creation of an optimized mixture of fuel and oxidant before contact with the catalysts, while preventing autoignition. 2004) High-Performance Solid Acid Fuel Cells Through Humidity Stabilization.

Like electric cars, electric bicycles are classified as zero-emission vehicles, meaning they emit no exhaust gases. If more road space were given over to them, and roads were designed with two-wheeled transport in mind, that might change. The reason is that western governments are not much interested bicycles.
million contract for design and construction of the Next-Generation Combat Engine. Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging.
The first such vehicles were introduced by Volkswagen in 2003, and by 2004, they accounted for more than 17% of the Brazilian auto market.
