Engine with overhead generator will be installed on the car "Chevrolet-Niva" 2004 model year. The first prototypes of the so-called "23rd" engine with overhead generator appeared in 1995. Then there were several series of refinement and the final revision took place a year ago. In just three months, "23rd" engine has been improved based on the pump power steering. This change was required under the terms of the contract for the production of "Chevrolet Niva" on the CJSC "GM-AvtoVAZ". On a new engine generator, water pump and power steering pump driven by a belt, and not two as previously. The traditional V-belt has been replaced by a new one - ribbed, which is used today throughout the world. V-belt drive reliability was inadequate, and the resource of a new, multi-ribbed belt is for the engine, said Alexei Palamarchuk, head of the upgraded engines of the Directorate of Technical Development of OJSC "AvtoVAZ". Moving the generator - not only processing engine. Vladimir Zolotouhin, a leading designer of the project, calls, among others, the following: an optimized engine intake tract, the electronic engine management system with multiple injection, a progressive chain camshaft drive (not used two-row, as the "classics", and single-strand chain), "Star" produced by advanced technology - accurate cutting of sheet steel with hardened teeth HDTV, hydraulic chain tensioner and hydraulic valve lever support, which eliminates the need for adjusting the clearance operations in the timing and lift chains. The technical level of the engine has increased substantially, said Vladimir Zolotukhin. Very soon, these engines will receive with AvtoVAZ joint venture to assemble "Chevrolet-Niv."
