– New Engine to Give New Impetus to Automotive Industry –

NISHINOMIYA, Japan, October 17, 2014 /PRNewswire/ — Namikoshi Electronics has started the development of a new engine with an innovative structure.

This engine was created for the generation of electrical energy, but we realized that it could also be used in automobiles. In light of rising fuel prices, the applications of this engine to motor vehicles would rival hybrid car engines in terms of efficiency.

This engine’s structure significantly reduces friction and vibrations which typically hinder power generation. Therefore, even in the case of equal fuel consumption, power will be increased compared to conventional engines.

1. Reduced friction

This feature is achieved because of fewer friction parts.
Ball bearings can be used. With ball bearings, friction can be further reduced.

2. Reduced vibrations

Thanks to the coherent rotation between dynamic balance and static balance, vibrations are highly improved.
Balance consistency makes vibration similar to the rotary engine’s.

3. Removal of round-trip kinetic energy generated by reciprocating motion

Pistons’ reciprocating motion generates round-trip kinetic energy between the crankshafts.
In this engine’s structure, the pistons’ kinetic energy directly offsets the balancer’s. Therefore, kinetic energy does not go through piston pins or crank pins.
As kinetic energy does not go through pins, there is no energy loss due to friction.

4. Expansive power is transmitted from one piston to another, reducing the loss of energy.

All four pistons are connected and incorporated as one. Expansive power is directly transmitted from one piston to the other three, reducing energy loss. In conventional structures, much energy is wasted as expansive power is transmitted through numerous mechanical linkages.
