  • As far as ignition systems, I wouldn't say thare are huge advancements. A cleaner burn is the key but the principle remains the same. in general chamber design, multi spark (petrol), better atomisation (Diesel- Increased rail pressure) the new atkinson cycle, variable valve timming, variable compression and so on. control of the EGR valve and the lambda sensor with inbuilt heater, they all combine to give a cleaner burn. of course the software plays a major role.. case in point VAG

  • In a petrol engine ignition system, a sparkplug is present on the top of the clynder head which ignites the charge i.e. a propotional  mixture of petrol and air, when compressed by the piston head in the clynder resulting in ignition
                                                                     whereas
    In a diesel engine ignition system, a fuel injector is present on the top of the clynder head which sprays diesel on highly compressed air done by the piston head in the clynder which reaches temperatures resulting in ignition.
