Perkins 4000 Series 4012-46TAG2A Diesel Engine Technical Data

Nov. 20, 2017

Research shows that Perkins team returns to Middle East Electricity (MEE) in 2017 to promote the full range of its diesel and gas electric power engines. Perkins 4000 Series has a high performance range from 6 to 16 cylinders, with exceptional power-to-weight ratios and a compact design, which makes it easy to transport, install and maintain. Every year, Perkins sells hundreds of 4000 Series engines into the prime power market. From the sentence below, you will see how powerful Perkins 4000 Series engines are!

“Today the 4000 Series is all about quality and reliability. Not just for standby, but for prime. Where quality and reliability are paramount, you can depend on the Perkins 4000 Series to keep the power on… permanently.”


4012-46TAG2A, as one of models of Perkins 4000 Series diesel engine, you will learn its technical data in this article.

Max breakaway current:

1600 amps

Cranking current:

Aids:

block heaters

Min mean cranking speed:

120 rev/min

 

Notes:

● The battery capacity is defined by the 20 hour rate

● z The oil specification should be for the minimum ambient

temperature as the oil will not be warmed by the immersion

heater

● Breakaway current is dependant on battery capacity available.

Cables should be capable of handling the transient current

which may be up to double the steady cranking current.
