Presentation

TD420VE, TAD420VE, TD520GE, TAD520GE and TAD520VE are in-line, direct injected, 4-cylinder industrial
diesel engines.

TAD620VE, TD720GE, TAD720GE, TAD720VE, TAD721GE, TAD721VE, TAD722GE and TAD722VE are in-line,
direct injected, 6-cylinder industrial diesel engines.

All engines are equipped with electronically controlled fuel management (EDC4), turbocharger, thermostatically
controlled cooling systems and electronic speed control. All TAD engines are also equipped with an intercooler.
