Publication number: 20140305393Abstract: An engine includes a cylinder head and a cylinder block connected to the cylinder head at an interface. A compression relief valve is substantially inset in the cylinder head of the engine. The compression relief valve is connected to an engine control module via a wire harness. The compression relief valve includes a body having a bore. Further, the compression relief valve includes a needle inset in the bore. The compression relief valve includes a compression relief valve sensor assembly disposed in at least one of the body or the needle. The compression relief valve sensor assembly is configured to generate a cylinder head temperature signal proportional to a cylinder head temperature at the interface.Type: ApplicationFiled: April 12, 2013Publication date: October 16, 2014Applicant: Electro-Motive Diesel, Inc.Inventors: Seema Farooqui, LeBlanc Martin, Farhan Devani, Aaron G.
