Maschninenfabrik Augsburg-Nuernberg (M.A.N.) of Germany has modified a truck-size diesel engine to consume only neat methanol by the addition of a transistorized spark ignition system. Regulated and unregulated exhaust emissions from this methanol engine with oxidation catalyst were characterized over the 1979 13-mode Federal Test Procedure (FTP), or shorter versions of this modal test, and over the 1984 Transient Heavy-Duty FTP. Emissions characterization included regulated emissions (HC, CO, and NOx), along with unburned alcohols, aldehydes, other gaseous organics, total particulate, sulfate, soluble organic in particulate, BaP, and Ames bioactivity. Emissions from this spark-ignited methanol-and-catalyst engine were compared to emissions from a pilot-injected methanol engine (dual-fueled) and a comparable diesel engine.
