Abstract
A fuel supply system of an engine designed as a gas engine or dual-fuel engine, has at least one solenoid valve. The solenoid valve is designed for introducing gas fuel into charge air or into a charge air line leading to at least one cylinder of the engine. The respective solenoid valve includes a valve body and an actuator with at least one magnetic plate and with at least one coil for actuating the valve body. The at least one solenoid valve of the solenoid valve is formed out of a corrosion-resistant material or is coated with a corrosion-resistant material.
Claims11
A fuel supply system of an engine configured as a gas engine or as a dual-fuel engine, comprising:
- at least one solenoid valve configured for use in a corrosive atmosphere, wherein the at least one solenoid valve is configured to introduce gas fuel into charge air or into a charge air line leading to at least one cylinder of the engine,
- wherein the respective solenoid valve configured for use in the corrosive atmosphere comprises:
- a valve body;
- an actuator with at least one magnetic plate that is exposed to the corrosive atmosphere;
- and
- at least one coil configured to actuate the valve body,
- wherein an entirety of the at least one magnetic plate of the respective solenoid valve, which is in direct contact with the corrosive atmosphere, is formed from a corrosion-resistant material or is coated with a corrosion-resistant material,
- wherein the at least one coil of the at least one solenoid valve is directly embedded in the at least one magnetic plate.
A fuel supply system of an engine configured as gas engine or dual-fuel engine, comprising:
- at least one solenoid valve configured for use in a corrosive atmosphere and configured to introduce gas fuel into charge air or into a charge air line leading to at least one cylinder of the engine,
- wherein the at least one solenoid valve configured for use in the corrosive atmosphere comprises:
- a valve body;
- an actuator with at least one magnetic plate;
- at least one coil configured to actuate the valve body;
- and
- at least one separating element, which is entirely planar and formed out of a corrosion-resistant material or is coated with a corrosion-resistant material and is configured to separate or seal the at least one magnetic plate from exposure to the corrosive atmosphere of the at least one solenoid valve from a corrosive atmosphere which is one of the charge air or a charge air-containing atmosphere.
An engine, namely gas engine or dual-fuel engine, comprising:
- at least one cylinder;
- and
- a fuel supply system, comprising:
- at least one solenoid valve configured for use in a corrosive atmosphere, wherein the at least one solenoid valve is configured to introduce gas fuel into charge air or into a charge air line leading to the at least one cylinder of the engine,
- wherein the respective solenoid valve configured for use in the corrosive atmosphere comprises:
- a valve body;
- an actuator with at least one magnetic plate that is exposed to the corrosive atmosphere;
- and
- at least one coil configured to actuate the valve body,
- wherein an entirety of the at least one magnetic plate of the respective solenoid valve, which is planar and in direct contact with the corrosive atmosphere, is formed from a corrosion-resistant material or is coated with a corrosion-resistant material.
