Abstract
A motor vehicle, which has a cryotank for supplying an internal combustion engine, includes an exhaust gas system including an exhaust gas catalyzer, a device for the combustion of boil-off gas from the cryotank, a gas duct, and a nozzle. The nozzle is configured to introduce the boil-off gas in the manner of an ejector pump into the gas duct which draws at least one of environmental air and scavenging air from a fuel supply system. The gas duct discharges near the exhaust gas catalyzer into the exhaust gas system.
Claims15
A motor vehicle with a cryotank for supplying an internal combustion engine driving the motor vehicle, with which an exhaust gas system having an exhaust gas catalyzer is associated, as well as a device for the combustion of boil-off gas from the cryotank,
- wherein the boil-off gas is introduced through a nozzle of an ejector pump into a gas duct which draws environmental air and/or scavenging air from the fuel supply system of a motor vehicle, and that the gas duct discharges near an exhaust gas catalyzer into the internal combustion engine's exhaust system.
A motor vehicle with a cryotank for supplying an internal combustion engine, comprising an exhaust gas system including an exhaust gas catalyzer, a device for the combustion of boil-off gas from the cryotank, a gas duct, and a nozzle of an ejector pump, wherein the nozzle is configured to introduce the boil-off gas into the gas duct which draws at least one of environmental air and scavenging air from a fuel supply system, and wherein the gas duct discharges near the exhaust gas catalyzer into the exhaust gas system.
A method for making a motor vehicle with a cryotank for supplying an internal combustion engine, comprising the steps of:
- comprising using a nozzle of an ejector pump to introduce boil-off gas into a gas duct which draws at least one of environmental air and scavenging air from a fuel supply system, and
- using the gas duct to discharge near an exhaust gas catalyzer into an exhaust gas system of the internal combustion engine.
