The VTMG engine

 

It is an internal explosion engine with movable cylinder head.Thus allowing the compression chamber volume is changing and be transferred. It this way five cycles for each revolution are obtained

1) Transfer 2) Explosion 3) Exhaust 4) Admission 5) Compression

Internal combustion engine already known (called two or four times engines) obtain their maximum compression when the piston is at its upper dead point , that means when the explotion takes place, that is to say when the moment of lever of the crankshaft and the connecting-rod is null. Therefore a large amount of power was lost in each explosion.

The VTMG engine makes the movable cylinder head work together with the piston and produces the explosion when there is a great moment of lever , thus obtaining high efficiency and fuel saving.

Its compression chamber has been tranferred from its upper dead point up to nearly 70º of the crankshaft turn. This is the Transfer  cycle added to the four ones already known , therefore each revolution has five cycles.

The movement of the movable cylinder head is obtained by means of a hydraulic mechanism.

Attention

The VTMG engine is a slow engine, but complies with the same rules of acceleration of a standard engines that accelerates to 4800 RPM.

Engine

 RPM Acceleration 1/6
Standard 800 RPM 4800 RPM
VTMG 400 RPM 2400 RPM

The VTMG engine is similar to the two stroke engine, by each turn of crankshaft produces an explosion, also we must keep in mind that it regulates halfway of turns than standard engine ; so 1200 RPM of the VTMG engine are equal to 4800 RPM of the standard engine.

 

 

Characteristics and Advantages of the VTMG engine

  • It is a small engine.
  • It is a very simple engine because it has less moving parts. (for example it has no distribution elements, refrigeration elements, battery, or driven valves).
  • It has a movable cylinder head.
  • It can graduates the volume of the compression chamber.
  • It transfers the compression chamber.
  • It has five stages or cycles. It adds a new stage, transfer, to the four ones presently known.
  • It produces explosion when the crankshaft in its turn reaches the best point of applying a force just exactly when the moment of lever of the crankshaft and the connecting-rod is at its maximum.
  • It saves fuel.
  • The crankshaft arm is longer, thus obtaining a higher lever arm making the most of the explosion energy.
  • The connecting-rod arm is much longer than conventional ones
  • Gases resulting from the combustion are completely swept away.
  • It heats much less.
