An internal combustion engine (ICE) may include various devices that may improve an efficiency of operation of the ICE. For example, an ICE may include a turbocharger device. The turbocharger device may improve an efficiency of the ICE by forcing air into a combustion chamber associated with the ICE.
Turbocharger devices may employ various components that may force air into a combustion chamber of an ICE. For example, a turbocharger device may include a turbine wheel, a compressor wheel, and a shaft. The shaft may connect the turbine wheel with the compressor wheel such that when the turbine wheel rotates the compressor wheel rotates.
Exhaust gases produced by the ICE may be routed to the turbocharger device where they may be used to rotate the turbine wheel. As the turbine wheel rotates it causes the compressor wheel to rotate. Rotation of the compressor wheel may cause ambient air to be pulled in and compressed by the turbocharger device. The compressed air may be pumped into the ICE's combustion chamber.
A speed sensor may be used to sense a speed of a turbocharger. For example, a turbo speed sensor may be used to sense a speed at which a turbine wheel and/or compressor wheel rotates in a turbocharger. The sensed speed may be used to measure a performance of the turbocharger.
A speed sensor may be manufactured using various over-molding processes. The over-molding processes may involve using various utilizing pressures and temperatures to accommodate the over-molding. The pressures and/or temperatures used for over-molding often are selected in order to obviate damage that may occur to the speed sensor during the manufacture of the speed sensor. Using too high of a temperature and/or pressure may cause damage to the speed sensor. However, using too low of a temperature and/or pressure may not provide a good seal for the speed sensor.
