Über dieses Buch

Owing 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 professionals in automotive engineering to manage without the corresponding expertise, whether they work 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.In this second edition, every section has been revised and expanded to include the latest developments in the combustion engine.

1. Piston rings

Without Abstract

2. Piston pins and piston pin circlips

Abstract
The piston pin is the link between the piston and the connecting rod. Owing to the oscillating motion of the piston and the overlay 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 rotational motion of the connecting rod relative to the piston must be compensated for at the bearing locations of the piston pin, in the piston pin boss, and the small end bore. Because of the small relative motions, the lubrication conditions here are poor.

3. Bearings

Abstract
Bearings are used to ensure the function 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 focuses on bearing shapes for engines and peripheral applications.

4. Connecting rod

Abstract
The connecting rod connects the piston to the crankshaft and consists of the small end and big end bores as well as the shank.

5. Crankcase and cylinder liners

Abstract
The crankcase is the central component of the combustion engine, containing and connecting the functional groups of the crank mechanism, 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 make use of the available installation space with the prerequisite of sufficient structural stiffness and with respect to the shape accuracy of the bearing and cylinder bores as well as the cylinder fit (for replaceable cylinder liners), with component mass as low as possible.
