Engine drive systems Technology and material changes Many components and systems in the engine depend on the correct functioning of the timing and auxiliary drives. This is also driving the technology and design of these systems, so they can live up to the more demanding criteria required. Timing drive system The controlled operation of this system is dependant on either a chain or a belt. A general drive for design improvement for performance gain, coupled with the pressure to reduce emissions, have seen twin overhead cam, multi-valve engines become commonplace. Timing belt A timing belt is typically rubber with high-tensile fibers (e.g. fiberglass or Kevlar) running the length of the belt. Rubber degrades with higher temperatures and contact with motor oil and antifreeze. Therefore, the life expectancy of a timing belt is lowered in hot or leaky engines. While older belts were of chlorobutadiene rubber material and trapezoidal shape, today’s modern belts are even more specific to particular engine designs, with subtle profile changes to the curvature of the teeth. In addition the improved material means these new designs optimize the power transfer without wear or noise, reaching ever higher lifespans in excess of over 93,000 mi/150 000 km. Timing chains Encased on the front of the engine, this power transmission drive frees up space to give the auxiliary system more space. On average, these chain systems have a longer life span on recent engines. The typical life of a chain is around 74,500 – 155,300 mi/120 000 km – 250 000 km. The disadvantage with chains is that they are noisy in comparison with belts and they lack the capacity to handle modern hp injection systems. In the immediate future (5–10 years), new cars sold with chains fitted on the engine drive system will rise by around 50%. Timing system, belts vs. chains For car manufacturers, engine assembly is all about numbers built – faster. Unfortunately, the time taken for the ABTU and belt on the timing system to be set up correctly, can eat into production time. Chains are easier and faster to install. This fact contributes to the use of chains today. The use of high performance material such as HSN, advanced automatic tensioner units, specialized bearings and pre-set tensioner springs for speedier and easier mounting, adds up to belt systems that reach the life time level of chains, while still offering design flexibility, cost and weight savings, as well as easier maintenance in the aftermarket. This is an advantage when it comes to car manufacturers’ choice. But, for now, chains are still the preferred option. Timing belt system Timing chain system 3
