70. p. 30-36.The gasoline engine has undergone intensive development in recent history with the introduction of technologies such as turbocharging and direct fuel injection. In addition to the reduction of part load fuel consumption, there is also significant optimisation potential for avoiding full load overfuelling and increasing low speed torque. Mahle will demonstrate in this paper that the introduction of technologies, used individually as well as in combination, can bring about an increase in torque at low engine speeds as well as reducing the requirement for over-fuelling.
