Solenoids for Motorcycle Engines

A manufacturer needed an automatic compression release valve for a motorcycle engine. TLX Technologies designed a solenoid valve that met all the requirements and reduced total vehicle cost.

Customer Problem

A manufacturer wanted to replace the manual compression release valve on a motorcycle engine with an automatic valve. The release valve vents the cylinder during start up, reducing the compression load on the starter system. The automatic valve needed to withstand the extreme conditions created by the engine, such as high temperatures and vibrations, while maintaining consistent operation over the part’s life cycle.

Before contacting TLX Technologies, the manufacturer approached several other suppliers and was told that it was not possible to manufacture such a valve.

The TLX Solution

TLX Technologies’ engineers were able to successfully design and produce an automatic compression release solenoid valve that satisfied all the requirements laid out by the manufacturer. The solenoid was able to:

Consistently operate at temperatures exceeding 572°F (300°C)
Withstand the vibration created by the engine
Fit into a smaller package size

The new solenoid designed and produced by TLX Technologies reduced the load on the starter. This required a smaller battery, starter motor, and alternator, resulting in lower total vehicle cost.

Our Process

Step 1 / Initial Review

Our engineering team works directly with you to determine the viability of your program and identify the best solution based on your specifications.

Step 2 / Quote

Quotes include all costs related to your project - tooling, prototype, piece part, production and project specific costs.

Step 3 / Design Review & Prototypes

Our engineering team reviews the design with you and makes any adjustments needed. Prototypes are built according to design specifications for testing.

Step 4 / Testing

Prototypes are tested according to your specifications, with all relevant test data provided to you for evaluation.

Step 5 / APQP

DFMEA’s, PFMEA’s, control plans and process flow diagrams are started to drive the product intent design.

Step 6 / Pre-Production

Working drawings are developed for production. A second prototype build and a set of production parts are made from tooling and thoroughly tested.

Step 7 / PPAP/Production

The final design along with the PPAP (Production Part Approval Process) is developed and the new product enters production.

Step 8 / Ongoing Improvements

Our team collaborates with you to continue making improvements to the product to best meet your needs, increasing efficiency and reducing cost.
