Abstract

A motor vehicle including an internal combustion engine, which utilizes a power take-off mechanism, that converts the reciprocating linear motion of the piston into reciprocating angular motion of the gearing cylinder, being in gear with the partially teethed connecting rod via right angled teeth and rotating motion of the drive shaft which runs coaxially through the gearing cylinder and vice versa. The mechanism has means for causing the piston to pause while the drive shaft rotates. The motor vehicle comprises a fuel heater, an exhaust cleaner including a sinuous tube and liquid for separating impure components of exhaust, a main control module controlling the function of the engine and piston function, a second control module controlling the engine during the minimal running state, thus controlling the pause time of the piston, a third control module controlling the energy flow to the heater, the fuel feeder, and the air feeder.

Dependent claims

A power take off mechanism for use with a reciprocating connecting rod to transfer reciprocating linear motion into rotating motion to rotate a drive shaft, the power take off mechanism comprising:

a partially-toothed gearing cylinder coaxial with the drive shaft that engages with a partially toothed portion of the reciprocating connecting rod to rotate the gearing cylinder in reciprocating angular motion independently of the drive shaft;
a first rotating boundary member, mounted to the drive shaft, so as to rotate in unison with the drive shaft;
and
a connecting system that operatively connects the gearing cylinder with the first rotating boundary member and with the drive shaft, the connecting system including a connecting roller that engages with a cylindrical aperture on the gearing cylinder to selectively engage the drive shaft into rotating motion;
wherein the reciprocating connecting rod includes a roller mechanism that engages a leaf shaped groove along at least one side of the first rotating boundary member, such that the leaf shaped groove defines limit points of the reciprocating linear motion of the reciprocating connecting rod and limit points of the reciprocating angular motion of the gearing cylinder;
wherein the leaf shaped groove comprises a path for the roller mechanism such that, when the partially toothed portion of the reciprocating connecting rod and the roller mechanism start linear motion towards a point on the leaf shaped groove that is closest to the drive shaft, the partially-toothed gearing cylinder starts angular motion and rotates in a direction of rotation of the driveshaft, thereby simultaneously causing the partially-toothed gearing cylinder to connect with the first rotating boundary member and the drive shaft to cause the drive shaft and the first rotating boundary member to rotate in a direction of rotation of the partially-toothed gearing cylinder.
