This project is comprised of five activities:
develop a cost-effective methodology to quantify the impact engine degradation
has on fuel efficiency and emissions; implement testing prior to service;
implement testing after service; compile the data, analyze results; and publish
the findings and the full data set.
Phase 1 – Methodology
· Develop a cost-effective methodology to quantify the impact engine
degradation has on fuel efficiency and emissions based on testing of engines
prior to scheduled servicing. Results
from these testing, events can be compared with manufactures original data
regarding fuel consumption rates and emissions (where available).
· Testing should also be implemented after servicing to quantify the
impact servicing has on fuel and emissions rates.
Phase 2 – Test planning/implementation
· Work with companies that rebuild marine engines to revise the methodology developed in Phase 1 to include their insights into the value of
maintenance and major rebuilds.
· Implement testing utilizing the revised methodology for 50 or more
marine engines. All sampled engines should be used to power vessels with dead weight
tonnage greater than 20,000 tons
Phase 3 - Analysis
· Compile the data, analyze results.
Phase 5 – Dissemination
· Identify potential users and notify them of the availability of
the draft report and data.
· Post the draft version of the findings and supporting data and
· Post final version that addresses comments received on the draft
version and post the final report on the TRB website.
