A direct injected engine includes a multi-layer support that attaches injector drivers to the engine while substantially isolating the injector drivers from high and low frequency vibrations. One layer of the support is formed of a relatively hard material so as to dampen high frequency vibrations produced by the engine when running at high speeds (e.g., 5300 rpm). A second layer of the support is formed of a softer material so as to dampen low frequency vibrations produced by another electronic control component, such as, for example, an electronic control unit (ECU), which the support also attaches to the engine. The ECU is disposed between the engine and a housing containing the injector drivers. The first layer of the support in this structure substantially isolates both the electronic control unit and the injector drivers from engine vibrations, and the second layer of the support substantially isolates the injector drivers from ECU-produced vibrations.
An engine comprising an engine body defining at least one variable-volume combustion chamber, at least one fuel injector communicating with the combustion chamber, an electronic control system communicating with the fuel injector, the electronic control system including at least one electronic component disposed upon a substrate, and a multi-layer support coupling the substrate to the engine, at least two of the layers of the multi-layer support having differing vibration damping effects.
An engine comprising an engine body defining at least one variable-volume combustion chamber, at least one fuel injector communicating with the combustion chamber, an electronic control system communicating with the fuel injector, the electronic control system including at least one electronic component disposed upon a substrate, and a multi-layer support coupling the substrate to the engine, a first dampener being arranged between the engine and a first layer of the multi-layer support, and a second dampener being arranged between the first layer and a second layer of the multi-layer support.
An internal combustion engine comprising an engine body defining at least one variable-volume combustion chamber, at least one fuel injector communicating directly with the combustion chamber, an electronic control system communicating with the fuel injector, the electronic control system including an electronic control unit and at least one injector driver disposed upon a substrate which is attached to the engine, and means for substantially isolating the injector driver from vibrations produced by the electronic control unit and from vibrations produced by the engine.
An internal combustion engine comprising an engine body defining at least one variable-volume combustion chamber, at least one fuel injector communicating with the combustion chamber, an electronic control system communicating with the fuel injector, the electronic control system including a first electronic component and a second electronic component, and an electrical component support structure mounted to the engine and comprising a first substrate and a second substrate, the first electronic component being disposed on the first substrate and the second electronic component being disposed on the second substrate, a dampener being disposed between the first and second substrates.
