An engine ignition coil assembly disclosed herein provides an ignition coil housing that may be mounted on an engine block assembly and that is isolated from engine vibrations. The engine ignition coil assembly comprises an ignition coil housing. The ignition coil housing contains an ignition coil apparatus. An electrical connector for the ignition coil apparatus is mounted to the ignition coil housing. An elastomeric boot supports the ignition coil housing and may be disposed on an engine block assembly such that ignition coil housing is spaced apart from the engine block assembly by the elastomeric boot. A single fastener extends through a fastener opening in the ignition coil housing parallel with the elastomeric boot. An elastomeric isolator is disposed on the ignition coil housing at the fastener opening around the single fastener. A proximal end of the single fastener may be fixed to the engine block assembly.

A camshaft (cam) phaser control system for an engine includes a first camshaft having a first target wheel. A second camshaft has a second target wheel. A cam position sensor detects said first and second target wheels and generates camshaft position data based on said first and second target wheels.

An automotive vehicle having a turbocharged internal combustion engine and a heat initiated exhaust treatment device, such as a catalytic converter, in the exhaust system is provided with a multiple function turbine bypass valve with controls that provide bypass of the exhaust gases directly to the treatment device during warm-up and also provide a boost controlling wastegate function that limits the turbocharger boost pressure during normal operation. Full throttle bypass override to provide turbocharger boost during warm-up as well as other control and operating functions are also disclosed.
