Product Overview

The DCM‑2316 (784570‑01) is NI powertrain‑grade embedded real‑time injector control measurement unit. It is specially designed for internal‑combustion‑engine test‑bench applications. It generates complex high‑speed drive waveforms for solenoid and piezo fuel injectors, meanwhile samples injector actual current feedback. Integrated Zynq real‑time processor + FPGA deliver nanosecond‑level timing precision for injection pulse control. It accepts crankshaft/camshaft position signal for engine phase‑synchronized firing sequence. Ethernet interface communicates with host test‑system; LabVIEW / powertrain control tool‑chain implements test‑sequence programming, parameter tuning and data loggingApollo Mea….

This hardware addresses engine‑test‑bench challenges: multi‑channel high‑voltage injector drive & measurement integrated in single unit, FPGA deterministic real‑time trigger, drop‑in spare‑part compatibility for legacy NI powertrain test‑system retrofit‑maintenance projects. Test‑bench & powertrain control engineers, laboratory‑maintenance technicians and retrofit integrators benefit most. Typical applications: gasoline/diesel injector test‑stands, engine‑ECU hardware‑in‑the‑loop (HIL) simulation systems, fuel‑system development validation benches.

Key Application Notes

• Specialized injector drive controller; cannot operate standalone. Requires host real‑time test system, external low‑voltage power supply, injector harness and matching solenoid/piezo injectors.
• Contains dangerous 250 V boost high‑voltage circuit; after power‑off, observe mandatory discharge waiting‑time before opening housing or touching output terminalsdownload.n…. ‑‑Not hot‑swap: fully cut off all power supply before unit replacement. ‑‑IO‑LOCK safety‑stop circuit must be wired per machine‑safety‑specifications. ‑‑Software configuration by NI Powertrain Controls tool‑set under LabVIEW environment. ‑‑Original OEM production discontinued; widely‑used aftermarket surplus/refurbished spare part for engine‑test‑bench maintenance‑retrofit projects. ‑‑Follow NI DCM‑2316 official user‑manual for harness wiring, high‑voltage safety procedure and injector‑waveform tuning.
