New Engine to Give New Impetus to Automotive Industry –
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.

Features
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.

5. Features of the engine

Weight:	Approx 90 kg. (machinery accessories are not included)
