Abstract
Abstract An improved Diesel engine supercharged by a turbo-compressor and corrected by a volumetric compressor corrector device driven from the engine crank shaft at a speed ratio which increases as the pressure delivered by the centrifugal compressor diminishes, in which an exchanger of heat with the cooling liquid of the engine is provided between the turbo-compressor and the volumetric corrector device, and in which the portion of the admission circuit comprised between the heat exchanger and the engine is provided with a heat and sound-insulation system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
In a Diesel engine provided with combustion chambers, a crank shaft, a circuit for the circulation of a cooling fluid, an admission circuit for a mixture of air and fuel, an intake manifold communicating with said combustion chambers through end connectors and an exhaust circuit of the type having a tuRbine operated by the exhaust gases, a centrifugal compressor driven by said turbine, a supercharging volumetric compressor corrector device driven by said crank-shaft at a speed ratio which increases as the pressure delivered by the centrifugal compressor diminishes, and an exchanger of heat with said cooling fluid, the provision of: a thermal-and-sound insulation of the portion of the admission circuit comprised between the heat exchanger and the intake manifold, said portion including said volumetric compressor.
Claim 2
Dependent Claim
125 words
In a Diesel engine provided with combustion chambers, a crank shaft, a circuit for the circulation of a cooling fluid, an admission circuit for a mixture of air and fuel, an intake manifold communicating with said combustion chambers through end connectors and an exhaust circuit of the type having a tuRbine operated by the exhaust gases, a centrifugal compressor driven by said turbine, a supercharging volumetric compressor corrector device driven by said crank-shaft at a speed ratio which increases as the pressure delivered by the centrifugal compressor diminishes, and an exchanger of heat with said cooling fluid, the provision of: a thermal-and-sound insulation of the portion of the admission circuit comprised between the heat exchanger and the intake manifold, said portion including said volumetric compressor.
Claim 3
Dependent Claim
29 words
A Diesel engine as claimed in claim 1 and further comprising a branch circuit for recycling the unvaporized fuel from the intake manifold, said circuit being also heat insulated.
Claim 4
Dependent Claim
33 words
A Diesel engine as claimed in claim 1, in which said insulation consists of a layer of a plastified product comprising a high proportion of an insulating product such as mica and/or asbestos.
Claim 5
Dependent Claim
42 words
An engine as claimed in claim 3, in which the insulating layer is applied so that it cannot be impregnated either with water or with fuel or with any other liquid product liable to deteriorate it or reduce its effectiveness and safety.
Claim 6
Dependent Claim
43 words
An engine as claimed in claim 1, in which said intake manifold is provided in the vicinity of said end connectors with a segregating longitudinal partition intended to retain the greater part of the liquid phase of the fuel in the admission circuit.
Claim 7
Dependent Claim
20 words
An engine as claimed in claim 1, in which the rocker-arm cover is sound-proofed by means of a suitable material.
Claim 8
Dependent Claim
37 words
An engine as claimed in claim 6, in which said sound -proofing material is the same as that of the insulation system of the portion of the admission circuit comprised between the heat exchanger and the engine.
