WebGenerally speaking, diesel engines are more fuel efficient than petrol engines. They use compression ignition (instead of spark plugs), which results in a more efficient fuel-burn. … Diesel enginesgenerally achieve greater fuel efficiency than petrol (gasoline) engines. Passenger car diesel engines have energy efficiencyof up to 41% but more typically 30%, and petrol engines of up to 37.3%, but more typically 20%. A common margin is 25% more miles per gallon for an efficient turbodiesel. Ver mais Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary … Ver mais Fuel efficiency is dependent on many parameters of a vehicle, including its engine parameters, aerodynamic drag, weight, AC usage, … Ver mais Energy efficiency is similar to fuel efficiency but the input is usually in units of energy such as megajoules (MJ), kilowatt-hours (kW·h), kilocalories (kcal) or British thermal units (BTU). The inverse of "energy efficiency" is "energy intensity", or the amount of input … Ver mais Measurement The fuel efficiency of motor vehicles can be expressed in more ways: • Fuel consumption is the amount of fuel used per unit … Ver mais Fleet efficiency describes the average efficiency of a population of vehicles. Technological advances in efficiency may be offset by a … Ver mais The specific energy content of a fuel is the heat energy obtained when a certain quantity is burned (such as a gallon, litre, kilogram). It is sometimes called the heat of combustion. There exists two different values of specific heat energy for the same batch of fuel. One is … Ver mais How fuel combusts affects how much energy is produced. The National Aeronautics and Space Administration (NASA) has investigated fuel consumption in microgravity. The common distribution of a flame under normal gravity … Ver mais
