The engine is designed for use in light-duty vehicles, and demonstrates the potential of modifying passenger vehicle engines to achieve diesel-like fuel efficiency and power using CNG as an alternative fuel. FEV developed ATAC more than a decade ago, targeting large-bore engines in stationary and heavy-duty applications.
The OP4 light-duty opposed-piston diesel. 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 dieselconceptengine, the OP4. DieselEngines Fuel Efficiency' Click to enlarge. Click to enlarge.
Motiv Engines, LLC introduced the second-generation of its engineconcept dubbed the MkII Clarke-Brayton Engine, which it intends to develop into a heavy-duty on-highway engine fueled by liquid natural gas (LNG). John Clarke presentation at Engine Stretch Efficiency Colloquium, 2010. and O’Malley, E.
Isuzu D201 35 hp dieselengine (left) and the LiquidPiston 40 hp X2 Prototype (right). HEHC is an improved thermodynamic cycle optimized for fuel efficiency that combines features of four existing cycles: High air compression ratio (Diesel). HEHC thermodynamic advantages relative to the diesel and the Otto cycles.
Detailed modeling of this approach undertaken through the Technology Strategy Board-funded “CoolR” project has suggested that efficiencies of more than 60% are possible, compared to around 40% for current dieselengines. Specific work available from an expansion over a variety of pressures for isothermal and adiabatic cases.
This new funding opportunity announcement will be available in early February. Area of Interest (AOI) 6: Electric Drive Vehicular Battery Modeling for Commercially Available Software. Battery models for this technical AOI will be made freely available to the public for battery pack design and analysis. turbomachinery.
At NACV, Bosch will debut its 15-inch freely programmable cluster, the largest digital cluster available for the commercial vehicle industry. At NACV 2017, Bosch is also showcasing several future-focused powertrain conceptsengineered to save fuel and money while extending the lives of fleets.
This means we have a responsibility to implement emission-lowering solutions available today while simultaneously developing solutions for tomorrow. MAN’s methanol-fueled ME-LGIM engine inherits well-known aspects and features of the standard MAN B&W two-stroke dieselengine. Source: MAN.
Unlike a spark ignition gas engine or dieselengine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. HCCI combustion can deliver a very efficient engine, potentially providing a 20% to 30% boost in gasoline engine efficiency without the NO x or PM emissions of a diesel.
