The Ford 1.8L Four Cylinder Turbocharged Diesel Engine for Passenger Car Application 901716
Sales of diesel passenger cars and car diesel derived vans has grown steadily in Western Europe throughout the 1980's and currently stands at some 16 percent of the West European Car market. The major advantages of the diesel are its excellent fuel economy and low gaseous emissions.
Excellent fuel economy, together with lower fuel costs in some markets, results in low operating costs when compared to comparable petrol engined vehicles.
The low gaseous emissions of the diesel become increasingly attractive as environmental pressures increase, particularly the low CO2 emissions which will be of increasing importance in the debate over the global ‘greenhouse effect’.
As the diesel market increases customer expectations become more critical. Given the diesels benefit of low operating cost and low emissions, the customer also expects levels of refinement (noise, vibration and harshness) and performance feel to be similar to those of the comparable petrol engined vehicle.
These considerations were of major importance in developing the 1.8L diesel engine family and dictated the need for engines which gave high power and torque at low smoke levels, low noise and emissions, whilst maintaining the 1.6L engines reputation for class leading fuel economy (1) and long life.
This paper concentrates on the development of the 1.8L turbocharged engine as fitted in the Sierra Car and P100 pick-up truck. The engine was developed at the same time as the naturally aspirated version (2) and shares many common design features.
