Embodiment Construction

[0035] In the following detailed description, the present invention will be described by way of preferred embodiments. Figure 1 discloses an existing engine which is taller and wider than the engine of the present invention.

[0036] FIG. 1 a discloses a large 12-cylinder two-stroke direct-flow purified diesel engine 1 arranged on a foundation 7 with main bearings for a crankshaft 22 . For ease of production, the base 7 is divided into several sections of suitable size. It consists of high-quality welded elongated channels and welded beams with cast steel bearing supports. The welded A-shaped crankcase structure 2 is installed on the base 7 . The crankcase structure is arranged between each cylinder, on which there are ribs arranged in the form of transverse plates 9, which are interconnected with the longitudinally extending outer wall 10 of the crankcase structure 2, and the transverse plates 9 are formed from the A-shaped crankshaft The top of the box structure 2 extends...

Abstract

The invention discloses a scavenging tank of a large two-stroke, uniflow scavenging type internal combustion engine and the cylinder frames (30 and 30') disposed on a frame (2) of a crank case of the engine, the cylinder frames (30 and 30') have an upper plate (31) having at least one circular hole (39) to receive and support a cylinder liner (6). The cylinder frames (30 and 30') further have a first side wall (32) having at least one port (38) to pass the scavenging. The scavenging tank (4) is directly fitted to the cylinder frames with a slender cavity facing the cylinder frames.

Description

technical field [0001] The invention relates to a purified air storage chamber for a large-scale double-stroke direct-flow purified internal combustion engine and a cylinder structure for being arranged on the crankcase structure of the internal combustion engine. The clean air receiver supplies clean air to the cylinders and supports the turbocharger and exhaust receiver. The cylinder structure forms a pedestal to support the cylinder liners, camshaft case and purge air reservoir. Background technique [0002] It is known from the "K98MC Project Guide for Two-Stroke Engines" ("K98MC Project Guide Two-Stroke Engines" 2nd edition l999, MAN B&W Diesel A / S) published in 1999 by MAN B&W Diesel A / S that it is used for large double-stroke engines. The purge gas reservoir of a single-stroke internal combustion engine is formed by a tubular elongate body extending along the entire length of the cylinder structure. The clean air storage chamber is provided with transverse ducts to ...
