Mechanical Variable Injection Timing (VIT) Technology to Reduce NOx Emissions

Sub-Grantees:Motive Engineering Co.

The principal objective of this program is to demonstrate a feasible low-cost, retrofittable technology for enabling Variable Injection Timing (VIT) in older diesel engines.  This entails showing that VIT will reduce NOx emissions with the best balance of cost, packaging and least impact on fuel consumption of the currently available choices.  The proposed program includes three phases whose objectives are listed below.

  • Phase 1: Determination of the benefits of variable injection timing
  • Phase 2: Proof-of-concept engine and preliminary testing for NOx reduction
  • Phase 3: Durability testing (to be proposed subsequent to Phases 1 and 2)
  • Phase 4: Verification testing (to be proposed subsequent to Phases 1 and 2)
