An evaluation of both raw and dilute engine exhaust sampling methods used to study the emissions is presented, along with the results and analysis of the initial screening tests on two four stroke gasoline outboard engines. the test results from the two engines reveal that the new testing capability is quite suitable to test and screen.

Pdf Emission Screening Test For Marine Outboard Engines Emission screening test for marine outboard engines. 2021 01 5016. the united states environmental protection agency’s (u.s. epa’s) national vehicle and fuel emissions laboratory (nvfel) has been developing new approaches for use in screening emissions from various types of new and in use (used) engines to investigate if their exhaust. Eive more rigorous compliance testing and analysis. in 2019, the epa finished developing a means to screen the emissions of marine outboard engines, including the use of specialized equipment. Figure 1. outboard engine test stand and exhaust ductwork ports. the vent was ducted to the "t" in the vertical section of ductwork. figure 1 is a photograph of the swri engine test stand and exhaust ductwork. 2192 be retained with these engines, the standard emission test practice of simply ducting engine exhaust to a. The engines are tested over five discrete steady state operating modes shown in table 5, known as the e4 composite duty cycle; the emissions results from these modes are then weighted to obtain a.

The engines are tested over five discrete steady state operating modes shown in table 5, known as the e4 composite duty cycle; the emissions results from these modes are then weighted to obtain a. Epa is regulating exhaust emissions from new spark ignition (si) marine engines for the first time. these standards apply for outboard engines, personal watercraft engines, and jet boat engines. this rule also adds a national security exemption for nonroad compression ignition (ci) and small si sectors. • 40 cfr 91.104 = outboard and personal watercraft (pwc) exhaust emission standards (1998 2009) • 40 cfr 91.105 = outboard and pwc useful life (1998 2009) • 40 cfr 91.1203 = warranty period (1998 2009) • 40 cfr 1045.103 = outboard and pwc exhaust emission standards (2010 ) • 40 cfr 1045.105 = sterndrive inboard exhaust emission standards.
