A prototype rotary valve engine has been built from a conventional single piston generator. In this study, an e ngine c ontrol u nit, ECU, is designed, tested and implemented for the purpose of carrying out the primary engine functions of sparking, f

The effects of the open-side end-wall and ground walls (planes) on the coupling between two identical combline resonators coupled through slots are analysed. It is shown that the electric coupling, which is necessary to realise filters with transmiss

A start-stop system (SSRE) is proposed for a newly designed camless rotary valve engine. The system is an improvement on the Mazda’s Smart Idle Stop System (SISS), a start-stop technology considered to be one of the best in the industry. Both syste

A camless engine using rotary valves has been proposed before and found feasible. In this paper, a single controller doing the primary engine functions of sparking, fuelling and valve events control is proposed. With no camshaft, only a crankshaft (o

A camshaft controlled car engine poppet valve system has been in use for many years since the industrial revolution. The crankshaft synchronously drives the camshaft using a timing belt. The camshaft in turn opens and closes the poppet valves during

Advances in mobile technology, due to the rapid growth of mobile wireless systems, coupled with stringent selectivity requirements, have led to the need for smaller and lighter high quality filters. The slotted cylindrical ring resonator is one reson
