Introduction

Jon C Darrow is a notable inventor based in Brighton, MI (US), recognized for his contributions to internal combustion engine technology. With a total of 6 patents, Darrow has made significant advancements that enhance engine performance and efficiency.

Latest Patents

One of his latest patents is focused on the detection of valve deactivation failure by monitoring exhaust temperature. This invention involves an internal combustion engine equipped with a temperature probe in the exhaust stream of a cylinder or a bank of cylinders. The Engine Control Module is programmed to monitor the rate of temperature change during valve deactivation and signal when the rate exceeds an acceptable range. This innovation serves as an indicator of failure in the Variable Valve Actuation (VVA) system, as a rapid decrease in exhaust temperature suggests improper valve deactivation.

Another significant patent by Darrow is a method for providing supplemental internal air cooling to multi-cylinder internal combustion engines. This method involves deactivating the fuel injector to one cylinder for a predetermined time, allowing cool air to be pumped through the cylinder by the piston’s reciprocating action. This internal cooling technique is particularly beneficial for motorcycle engines operating at low speeds, such as during parades or ceremonial functions.
