- TURBO CHARGER INTRODUCTION
Turbochargers have become an almost indispensable tool in the race to reduce engine emissions and comply with increasingly stringent pollution standards. The Euro IV emission standards began to make things difficult for vehicle manufacturers, who have since had to work hard to meet and overcome the latest challenges.
The turbo is a component that was popularly fitted to petrol engines to increase power regardless of the increase in either fuel consumption or emissions. When turbos were fitted to diesel engines, we began to understand that turbocharging did not necessarily mean increased fuel consumption.
Thanks to technological developments such as direct injection, Variable Valve Timing (VVT), or the use of the Miller cycle, turbos can help to achieve lower emissions and increase vehicle performance at the same time. This is why over 70% of all new vehicle registrations are fitted with a turbocharging system.
Since the introduction of the Gates Turbo Hoses range, more than 1,000 references have been added. Another 200 will be added by the end of 2023, which demonstrates a clear commitment to the range.
All vehicle parts are subject to wear and tear, and turbo hoses are no exception. As we saw in our previous article on turbo hoses, expansion and contraction under pressure, coupled with the high temperatures of the compressed gases and the presence of oil inside the intake circuit, causes the hoses to wear more quickly and eventually fail. Moreover, in cases where hoses are fitted with fixing clips, further problems may arise. As well as being subject to wear and tear, the clips are sometimes mishandled and damaged as consequence of poor workshop practices during standard maintenance procedures.
The fixing clips allow quick assembly of any hose. Just push the hose into the aperture and it locks. The part is fitted correctly, quickly and easily.
The fixing clip comprises of a metal rod, reformed into a square-shaped arrangement (see image above). The right-angled corners prevent the sleeve from slipping and sliding out of place. The clip is designed to remain immobile when the engine is running. However, vibrations from the engine have been known to ‘round’ the edges of the clip. If this occurs, the fastening becomes loose. The result is a loss of pressurized air.
Poor workshop practices when fitting and removing the clips can cause deformities. When removing the sleeves, lift the clip carefully to release the grip, but ensure that it remains lodged in the holes. This allows free movement. The sleeve can be safely removed. Never use a screwdriver to release the temples of the clip. This is likely to lead to deformity and potential failure. If the clip loses its grip on the sleeve, it is likely to be ejected from its housing once pressure enters the system
