Which engine is more powerful diesel or petrol?

Both produce same power, but diesel produces more torque at the expense of speed whereas petrol engine it is vice versa. Diesel swift is more powerful than petrol. Petrol is fast but diesel is power full as all heavy vehicles are of diesel and normally cars and motor bikes are in petrol.

What is the most efficient type of engine?

Focus on sustainability. As emissions are caused by burning fuel,it is only natural that an engine that consumes considerably less fuel also produces significantly fewer emissions.

  • Less maintenance,more uptime.
  • Modular design.
  • Operational flexibility.
  • “Future-proof” engine.
  • Three engines,one common platform.
  • Less energy,costs,downtime and emissions.
  • What is the most efficient engine design?

    Hybrid Engines. One of the biggest engine improvements used to boost efficiency in recent years is the hybrid engine.

  • Clean Diesels. An Audi Q7 TDI clean diesel on display at Grand Central Station in New York City.
  • On-board Engine Computers.
  • Variable Valve Timing.
  • Overhead Camshafts.
  • Aluminum engine blocks.
  • Direct Injection.
  • Fuel Injection.
  • Forced Induction.
  • What is the thermal efficiency of diesel engine?

    The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air.

    How efficient are engines?

    Engine efficiency refers to an engine’s ability to transform the available energy from its fuel into useful work power. The modern gasoline combustion engine operates at an average of roughly 20 to 30 percent engine efficiency. The remaining 70 to 80 percent of the gasoline’s heat energy is expelled from…
