Self Study Program 223 – The 1.2l and 1.4l TDI engines With Pump Injection System Design and Function PDF free online
Following the successful launch of 1.9l 4-cylinder TDI engines with unit injector system in the Golf and Passat, the trend towards economical, low-emission and simultaneously powerful direct-injection turbodiesel engines is continued in the Polo and Lupo by the 3-cylinder TDI engine.
By eliminating a single cylinder, the engines are now lighter, have fewer moving masses and produce less friction than a 4-cylinder engine. Despite their lower displacement, they have a high performance potential for this vehicle class.
Particularly in the 1.2l TDI engine developed specially for the Lupo 3L, numerous new
technologies and production methods have been employed in order to achieve the development goal of reducing fuel consumption to 3 litres per 100 km. This consumption figure was made possible by saving weight, reducing friction and improving the combustion process.
In this Self-Study Programme, you have the opportunity to familiarise yourself with this new engine generation, which is exemplified by the 1.2l and 1.4l TDI engines.
