Development of On-board generator Using Ceramic linear engine For Neighborhood ElectricVehicle
In the realm of small electric vehicles (neighborhood electric vehicles or personal electric vehicles such as electric wheelchairs, electric scooters etc.), there’s a power struggle brewing. They demand lots of electrical power and long operation, but current rechargeable battery cannot provide the operational durations required. Also short lifetimes of batteries impose a fundamental limitation. Due to these reasons, a small linear reciprocating engine and linear electric generator are designed in this paper. If an engine is used solely to produce electrical power, it is not necessary to convert the reciprocating linear motion of the piston to rotary motion by crank. Instead, a linear electrical generator may be coupled directly to the piston for a conversion of mechanical energy into electrical energy. Such a design has many advantages such as mechanical simplicity and low friction and it can make possible a small engine having high efficiency. In other words, linear engines give power output more efficiently compared to conventional reciprocating piston engine, because it doesnt have a crank mechanism, hence there is less mechanical loss. In this study, we developed a small sized linear engine generator for the electrical power generation. To increase the efficiency and endurance, we made a piston and cylinder sleeve by ceramic materials.
