Estimating the term…
The invention relates to an internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a crankcase ventilation means, wherein the crankcase ventilation means is open, closed or separate. The internal combustion engine according to the invention comprises an intake path, a crankcase, an exhaust gas path and an open crankcase ventilation means, wherein the open crankcase ventilation means comprises a first line and a second line, wherein the first line is designed to connect the exhaust gas path to the crankcase in order to guide exhaust gas out of the exhaust gas path to the crankcase, and wherein the second line is designed to connect the crankcase to the exhaust gas path in order to discharge exhaust gas and leakage gases located in the crankcase from the crankcase and to feed them to the exhaust gas path.
An internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and an open crankcase ventilation means, wherein the open crankcase ventilation means comprises a first line and a second line, wherein the first line is designed to connect the exhaust gas path to the crankcase in order to guide exhaust gas out of the exhaust gas path to the crankcase, and wherein the second line is designed to connect the crankcase to the exhaust gas path in order to discharge exhaust gas and leakage gases located in the crankcase from the crankcase and to feed them to the exhaust gas path.
An internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a closed crankcase ventilation means, wherein the closed crankcase ventilation means comprises a first line and a second line, wherein the first line is designed to connect the intake path or the exhaust gas path to the crankcase in order to guide fresh gas out of the intake path or exhaust gas out of the exhaust gas path to the crankcase, and wherein the second line is designed to connect the crankcase to the intake path in order to discharge fresh gas or exhaust gas and leakage gases located in the crankcase from the crankcase and to feed them to the intake path.
An internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a closed crankcase ventilation means, wherein the closed crankcase ventilation means comprises a compressor and also a first line and a second line, wherein the first line is designed to connect the compressor to the crankcase in order to guide fresh gas from the compressor to the crankcase, and wherein the second line is designed to connect the crankcase to the intake path in order to discharge fresh gas and leakage gases located in the crankcase from the crankcase and to feed them to the intake path.
An internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a separate crankcase ventilation means, wherein the separate crankcase ventilation means comprises a device for removing fuel and also first line and a second line and the first line and the second line are designed to conduct a substantially inert gas, wherein the first line is designed to connect the device for removing fuel to the crankcase in order to guide the substantially inert gas from the device for removing fuel to the crankcase, and wherein the second line is designed to connect the crankcase to the device for removing fuel in order to discharge the substantially inert gas and leakage gases located in the crankcase from the crankcase and to feed them to the device for removing fuel.
