Convert Text to Table In a comparison of Ford Conventional vehicles and hybrid electric vehicles (HEV) the HEV proved to have a greater range (450-550 miles) than did the conventional vehicle (350 miles). And, as might be expected, these numbers were the same for gasoline range. In terms of economy, the HEV was 30-50% better than the conventional vehicle. This in turn, meant less frequent fill-ups for the HEV. Burning less gasoline causes the HEV to be 95% cleaner-far friendlier to the environment. And finally, this study found that the HEV performed more like a V-6 (more powerfully) than the conventional vehicle, whose performance was considered more like that of a 4-cylinder engine.

Task 8 - Induction Systems In order for combustion to take place an induction system is required to feed fuel and air into the cylinder of an engine. To improve efficiency and performance spark ignition (SI) engines are now adopting compression ignition (CI) engine technology by injecting fuel directly into the cylinder just before the point of ignition however these engines still require an air induction system. Carburettors: before fuel injection technology had been fully developed carburettors (carbs) were used to create a fuel/air ratio at different engine speeds and loads. A cold start facility was also fitted albeit manually operated. The demand for more performance has meant the fixed choke carb' was no longer suitable. More complex carbs' were developed (twin choke) as well as variable choke (constant depression) carbs which used engine vacuum (during throttle opening) to vary the size of choke according to operating requirements.
