The EVC 80 main
With lower amperage, EVC 80 can be the main power contactor in a hybrid-electric vehicle from the battery to the car, or an auxiliary unit contactor in a
Designed for OEM bus electrical center applications (BECs), this plug-in contactor is non-polarity sensitive, providing ease of installation for coil power. A shielded outer core offers enhanced electromagnetic compatibility capabilities.
Electric air conditioning compressor
Electric compressors for automotive air conditioners have been certified compliant with Automotive Software Process Improvement and Capability dEtermination (SPICE) Version 3 (Level 3) standards – informal regulations set for the in-vehicle software development processes formulated by European car manufacturers. Certification was provided by DNV GL, a third-party certifying body based in Norway.
Automotive SPICE Ver. 3 verifies Level 3 compliance for 17 processes, including project management, software requirement analysis, software architecture design, software integration and integration testing, software competency testing, and quality assurance.

Commercial vehicle piston ring
A piston ring for commercial vehicle diesel engines enhances gas sealing capability by stabilizing ring dynamic motion and homogenizing oil film. The running surface profile of eLine rings, used in the 2nd groove, distributes oil more evenly around the cylinder bores and modifies the running face area for reduced gas pressure force. This enhances engine efficiency, increases robustness, and lowers emissions. Bench tests with eLine in different diesel engines have reduced blow-by up to 20%, which converts directly into increased mean effective pressure or decreased fuel consumption.
Rings used in the 2nd groove of commercial vehicle engines typically feature a tapered running face profile that can fail to produce a homogenous oil film. The relatively large running face area can cause radial ring instability when
