This corresponds to a 23% reduction in fuel consumption and, therefore, CO 2 output.). From a powertrain frame of reference, Mazda is planning a building block strategy—i.e., Ultimately, the compression ratio ended up playing a central role among these factors in both gasoline and diesel engines, although in different directions.

Offered in three models with gasoline or electric propulsion, the updated Kona will be an important part of the growing Hyundai electrified line-up. This design strategy is opposite of what most traditional car companies have done, which is design first for a gasoline engine, and then adapt it to an electric power plant.

The Charter matches fuel specifications to the vehicle and engine specifications required to meet various customer needs around the world. Increasing the minimum octane rating available in the marketplace has the potential to help vehicles significantly improve fuel economy and, consequently, reduce vehicle CO 2 emissions.

The high-level performance goals of the Partnership are a 25-40% improvement in fuel economy in a light-duty vehicle (LDV) and achieving 55% brake thermal efficiency (BTE) in heavy-duty engine systems. Development of low temperature combustion (LTC), learn-burn gasoline combustion and development of alternative (e.g.,

A study of isopentanol—a five-carbon, long-chain alcohol (C 5 H 12 O)—by researchers at Sandia National Laboratories as a fuel for homogeneous charge compression ignition (HCCI) engines found that isopentanol has superior physiochemical properties compared to ethanol and very similar HCCI combustion properties to gasoline.

One focus of the project will be centered on light- and heavy-duty vehicles running on gasoline/ethanol blends in order to improve engine efficiency and lower emissions. The fundamental physics behind flame propagation through a stratified charge will be studied to obtain a comprehensive description of the PFS ignition process.

Pressure on the RFS2 has increased as statutory mandated volumes of biofuel exceed the “blendwall” of 10% ethanol in gasoline. Primary technical concerns with using intermediate-level blends of ethanol in the vehicle fleet include: Fuel economy. the optimal air/fuel ratio for ethanol blends is lower than for pure gasoline.
