  1. "I think the human race made a big mistake at the beginning of the industrial revolution, we leaped for the mechanical things, people need the use of their hands to feel creative." - Andre Norton

  3. Diesel or kerosene has no spark plug due to its higher volatility and flash point. The spark plug and voltage needed for ignition would be very large. So the atomized fuel-air mixture is ignited (adiabatic heating) by superheated, compressed air. The compression ratio for diesel is higher to ensure more complete combustion, which helps it have a much improved thermal efficiency over CI engines.

  4. Because here ignition takes place at a very high compression ratio where the temperature is high enough for self ignition of the diesel(fire point) air mixture to takes place....

  5. Tyres are mixture of various rubbers with carbon black added. Carbon black improves traction and wear resistance of pure rubber. Another reason is that black color has higher absorption capability by which the tyre of any vehicle becomes adhesive to road

  6. In DTSi, instead of 1 we are using 2 spark plugs. Flame front formed is able to consume more air-fuel mixture as compared with 1 spark plug, thus more complete burning and more efficiency. in DTS-Si, with addition of 2nd spark plug, what they are doing is relocating valves position. With proper designing of inlet and outlet valves you can induce extra swirl for inoming air fuel mixture. Due to turbulence, extra efforts are provided for proper mixing of air and fuel. (We can not allow petrol to go in liquid droplet form, it should be finely atomized). With well atomized air fuel mixture, efficiency increases.
