Abstract
Abstract The air intake of a diesel engine used as a main power device is connected to a supercharger air outlet, wherein the supercharger is driven by an spark ignition engine. Discharged air from the supercharger is directed to an inlet system of said diesel engine for said main device by a pipe. Exhaust gas from the spark ignition engine is supplied between an inlet system of the supercharger and an inlet system of the diesel engine via an exhaust regulating valve. The regulating valve is regulated according to the operating condition of said diesel engine. Without deterioration in diesel engine startability and output, the engine system provides overall exhaust treatment which decreases especially NOx.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
91 words
An engine system, comprising: a main device diesel engine; an auxiliary device spark ignition engine; a supercharger connected to and driven by said auxiliary engine; an air inlet leading to said supercharger; a supercharger outlet for discharging air under pressure from said supercharger; an inlet system for said main device diesel engine for receiving air from said supercharger outlet; and means supplying exhaust gas from said spark ignition engine to said air inlet of said supercharger to thereby supply spark ignition engine exhaust to the inlet system of said diesel engine.
Claim 2
Dependent Claim
91 words
An engine system, comprising: a main device diesel engine; an auxiliary device spark ignition engine; a supercharger connected to and driven by said auxiliary engine; an air inlet leading to said supercharger; a supercharger outlet for discharging air under pressure from said supercharger; an inlet system for said main device diesel engine for receiving air from said supercharger outlet; and means supplying exhaust gas from said spark ignition engine to said air inlet of said supercharger to thereby supply spark ignition engine exhaust to the inlet system of said diesel engine.
Claim 3
Dependent Claim
44 words
The engine system as claimed in claim 1 further including an exhaust regulating valve connected between said auxiliary device spark ignition engine and said inlet system of said diesel engine, the regulating valve being regulated according to an operating condition of said diesel engine.
Claim 4
Dependent Claim
41 words
The engine system as claimed in claim 1 further including means regulating a load of said auxiliary device spark ignition engine, whereby discharged air pressure from said supercharger is changed and the output of the main device diesel engine is regulated.
Claim 5
Dependent Claim
23 words
The engine system as claimed in claim 1 wherein the compression ratio of said main device diesel engine is between 10 and 14.
