Über dieses Buch

Due to the ever increasing requirements to be met by gasoline and diesel engines in terms of CO2 reduction, emission behavior, weight, and service life, a comprehensive understanding of combustion engine components is essential today. It is no longer possible for a professional in automotive engineering to manage without the corresponding know-how, whether that is in the field of design, development, testing, or maintenance. This technical book provides in-depth answers to questions about design, production, and machining of cylinder components.

1. Piston rings
Abstract
Piston rings are mostly single-piece, slotted, and self-tightening. Their basic shape is a thinwalled, axially short circular cylinder. To generate the necessary contact pressure against the cylinder wall, the piston rings are in the shape of an open circular spring. The spring force acting radially in the installed state is greatly amplified by the gas pressure behind the piston ring.

2. Piston pins and piston pin circlips
Abstract
The piston pin is the link between the piston and the connecting rod. Due to the oscillating motion of the piston and the interaction of gas and inertial forces, it is subjected to high loads in alternating directions. Figure 2.1 shows the piston pin load for a gasoline engine at rated power. The rotary motion of the connecting rod relative to the piston must be compensated for at the bearing locations of the piston pin, in the pin boss, and the small end bore. Due to the small relative motions, the lubrication conditions here are poor.

3. Bearings
Abstract
Bearings are used to ensure the functional strength of the movable connection between two components. In general, different types of bearings include roller, plain, air, liquid, and magnetic bearings. The MAHLE product range comprises many typical bearing shapes for engines and other applications.

4. Connecting rod
Abstract
The connecting rod connects the piston to the crankshaft, and consists of the crank or big end, pin or small end, and shank.

5. Crankcase and cylinder liners
Abstract
The crankcase is the central component of the internal combustion engine, containing and connecting the functional groups of the crank drive, and forms a system boundary that seals off the combustion engine externally. It prevents exit of the working medium, coolant, and lubricant, and the entry of moisture and dirt. The crankcase must utilize the given space at the lowest possible part mass, while maintaining sufficient structural stiffness and the shape accuracy of bearing bores and cylinder fit (for replaceable cylinder liners).
