VHP Series 2 to Series Four Conversion
INNIO’s VHP* Series Four* upgrade packages offer the latest technology with field-proven Series Four heads. Options include an upgrade to the scuff-resistant Series Four piston, and a full Series Four power upgrade option with up to an additional 200 bhp. Each of these product features can be combined or used separately to upgrade your existing VHP Series 2 gas engine. With these upgrades, you can expect to see increased uptime, reliability, and performance.
What can this upgrade do for you?
- More uptime due to longer intervals between overhauls. Up to 60% longer intervals between top-end overhauls; up to 32,000* hours on L7042GSI S4 vs. 20,000 hours on existing L7042GSI engines.
- Lowered lifecycle costs through lower oil consumption. S4 pistons feature increased scuff resistance and three-ring design, which can reduce oil consumption by up to 67%, reducing makeup oil cost and catalyst masking.
*Intervals may vary depending on factors such as fuel quality, maintenance practices, and operating conditions.
Engine configuration must be verified for upgrade opportunity.
