An engine with a slider-crank mechanism, comprising a housing, containing a shaft with a crank, and at least two cylinders with pistons mounted on rods, the ends of which extend from the pistons through guide bushings of the cylinders and are connected to one another by means of a yoke assembly. A housing of the yoke assembly is configured in the form of a frame having a rectangular cross-section and inner guiding surfaces for a block slider mounted with freedom of movement between said surfaces and with freedom of rotation on the crank of the shaft. The block slider is comprised of two connected halves with grooves for lubricating an outer sliding surface. The housing of the yoke assembly is mounted such that its lateral surfaces are disposed between guiding surfaces inside the engine housing.

The present invention provides a more accurate device and method for measuring automobile horsepower, specifically the internal combustion engine, ICE horsepower at the crankshaft, or the electric motor(s') horsepower, or the combined ICE and electric motor(s') horsepower. It applies to automobiles that do not incorporate, or can disengage, regenerative braking, RGB. The proposed device and method measures horsepower in real road test conditions, through the utilization of an accelerometer that performs measurements of the automobile velocity, acceleration and deceleration, whereas the method provided may be also applied to chassis dynamometers, resulting into a more accurate horsepower measurement by such dynamometers.

A four-stroke opposed-piston engine contains a cylinder having a periphery and a combustion chamber and an ignition system, wherein the ignition system is fixed to the cylinder periphery and at least partially contained within the combustion chamber. During combustion, the ignition system is adapted to locate a spark within a fuel-rich predetermined region of the combustion chamber.
