Cummins K19 — the 19-litre family
The 19-litre K family table: nine listed steps from the KT19-C450 at 335 kW to the KTTA19-C700 at 522 kW, all at 2,100 rpm.
The K19 family is where this catalogue's Cummins line moves into heavy power. Its listed table runs from the KT19-C450 at 335 kW to the KTTA19-C700 at 522 kW, on bore and stroke of 159 × 159 mm and a displacement of 19 litres, at 2,100 rpm. The variant codes carry the family's structure in their names — KT, KTA and KTTA steps — and the table's job is to let you place your requirement on the right step.
Engines of this class are bought for mining, heavy construction, large gensets and industrial drives, and they are bought slowly and carefully: a K19 enquiry normally involves a machine or project specification, a rating confirmation and a scope-of-supply discussion. The listed table band and dimensions are set out below; ask for the full variant row for your step to be stated in the quote, in writing, before an order is placed.

Specifying a K19
Start from the variant code of the engine you run or the project specification you hold, not from the band edges. The listed steps between 335 and 522 kW correspond to distinct variant codes with distinct rating points, and a quote built on the wrong step misprices the project and mis-specifies the installation. Send the full variant code, the application (machine, genset or industrial drive) and the duty, and have the exact row — rating, speed and scope — restated in the quote.
For genset applications at this size, the rating basis question from the smaller families matters even more: confirm whether the quoted figure is a standby or continuous rating for the specific variant, at your frequency. The listed table here is quoted at 2,100 rpm machine speeds; for genset variants, ask for the figures for your application in the enquiry.
How buyers spec this line
- Quote the full variant code (KT/KTA/KTTA step), not just 'K19'.
- Listed dimensions: 159 × 159 mm, 19 L, at 2,100 rpm.
- Confirm rating basis (standby vs continuous) for genset projects.
- QSK19 is a separate sibling family — do not mix tables.
Terms on record
Listed terms on record: complete engines and power units carry a delivery window of 15–30 days and a warranty of 1 year or 1,200 hours, whichever comes first, as published in the supplier's FAQ. Confirm the exact rating, scope of supply and delivery window for your model before you order.
Buyer questions
K19 or QSK19 — which table applies?
The one matching your engine's designation. They are sibling 19-litre families with separate listed tables (K19: 335–522 kW; QSK19: 340–597 kW band).
What is the largest K19 listed?
The KTTA19-C700 at 522 kW, at 2,100 rpm.
Can a K19 power a large genset?
That is a variant question, not a family claim: state frequency and duty and have the variant and its rating basis confirmed in the quote.
