2/4 Project To Discuss Engine Of The Future The Institution of Engineering and Technology (IET) will stage a free event on the theme of the future of engine design on 16 June, at the Novotel Hotel, Hammersmith, London, UK. The 2/4 Car project aims to prove that a gasoline engine, by combining two- and four-stroke operation, can be downsized sufficiently to compete with future diesel power in terms of CO2/cost trade-off. This study of 2S-4S gasoline engines has culminated in the development of the multi-cylinder 2/4Sight engine. This engine is based on a 2.1-litre V6 gasoline unit with direct injection, an electro-hydraulic valvetrain and an advanced boosting system. Guest speaker Bob Gilchrist will explain the results of the 2/4Sight simulation and engine testing programmes. His presentation will include updates on the 2/4 Car programme to provide a demonstration vehicle for 2011.

Trelleborg Automotive has developed a damping plate that allows PSA Peugeot Citroen to reduce noise and vibration caused by diesel-engine knocking. Trelleborg Automotive used its NVH experience to produce a specially-cut shear plate, engineered using the company's Duru-LAM material. Resistant to both heat and oil, Duru-LAM is a proven material for damping sound and vibrations in internal engine applications and, in the shear plate design, it comprises a layer of rubber sandwiched between two layers of steel. The shear plate is then positioned according to the packaging requirements of different core engine designs and can be used in gasoline, as well as diesel variants. Arvid Norberg, research and development NVH manager at Trelleborg Automotive, said: 'The conventional solution to reduce vibration is to increase engine block stiffness, but in many cases this only shifts the noise to higher frequencies. 'The introduction of the shear plate enables us to reduce vibratio...
