摘要： In one embodiment, a sensing apparatus senses rotation of an engine component (e.g., a crank shaft) relative to an engine body. The sensing apparatus includes a sensor, and a bracket configured to position the sensor in a fixed location relative to the engine body. The starter ring has (i) a support portion configured to rotate in tandem with the engine component, (ii) a starter interface mounted to the support portion, the starter interface being configured to receive drive from a starter motor during operation of the starter motor, and (iii) a trigger portion mounted to the support portion. The trigger portion is configured to provide a series of indicators during rotation of the engine component. The series of indicators (e.g., a series of magnetic field perturbations during rotation of the engine component) is readable by the sensor thus enabling identification of component positioning and speed.

摘要： An internal combustion aircraft engine comprising a cylinder head having a cylindrical head bore formed therein, a piston, and spark plugs, the cylinder head bore and piston designed to reduce engine knock. The cylinder head is fixedly attached to a top end of a cylinder barrel formed with cylindrical walls, the cylinder head bore and the cylindrical walls defining a cylinder. The cylinder head bore has formed therein an outwardly protruding cavity with respect to the top end of the cylinder barrel. The piston has a piston crown, and the piston contained within the cylinder, the piston crown, the cylinder walls, and the cylinder head bore define a combustion chamber. The piston crown has a concavity formed therein, and the piston is constructed and arranged to reciprocate within the cylinder. The concavity of the piston crown and the cavity cooperate at a top dead center position of the piston to form a swirl chamber. The piston crown has formed along a peripheral edge thereof a squish area that corresponds to a second squish area formed in the cylinder head bore, so that when the piston approaches top dead center, the squish area and the second squish area cooperate to cause combustion gases to move radially inward of the combustion chamber and into the swirl chamber. Spark plugs extend through the cylinder head, the tips of which are disposed within the swirl chamber.
