Hatz B-Series 1B30 Air-Cooled Single-Cylinder Diesel Engine
Description
A compact air-cooled diesel for vibration plates, pumps and generator sets
The Hatz 1B30 is the reference model of the Hatz B-Series, a family of single-cylinder, air-cooled, four-stroke direct-injection diesel engines for mobile and stationary machinery with a power requirement up to about 8 kilowatts. Hatz describes the series as having been used in everything from vibration plates to polar conditions, and its short overall length comes from the patented Single Cam System, in which one cam and rocker arms operate both the injection pump and the valves on the mechanically controlled engines.
This page covers the series as printed in the manufacturer data sheet: 1B20, 1B30, 1B30E, 1B30VE, 1B40, 1B50 and 1B50E. The E versions belong to the Hatz E1 family with electronic injection and a standard J1939 CAN interface; the others are mechanically controlled. All seven share the same basic power train, so displacement and installation space can be matched to the machine.

Variants, control and emissions
Three engines in the series carry the E1 electronics: the 1B30E, the 1B30VE with vertical crankshaft and the 1B50E. The data sheet states that they are controlled through the ECU over CAN J1939 and can drive CAN displays, and that the E1 models meet EPA Tier 4 final and EU Stage V, including at variable speed. Mechanical engines use a stage switch or analogue speed control. The data sheet also lists an optional silent noise package that lowers noise by 2 to 4 dB(A) on suitable types, and a 1B50E version with a passive diesel particulate filter for EU Stage V in defined applications.
Several power take-off options are drawn in the data sheet, including cylindrical shafts of 19.05, 25.4 and 25 mm with keyway, conical shafts and SAE generator flanges, with a permanent magnet alternator of 2 to 7 kW mountable on the flywheel side. Hatz builds its flywheel-integrated generator (fiPMG) on the 1B30E and 1B50E; that is listed separately on this site.
Selecting a B-Series engine
Start from the power and speed the driven machine needs, then check the rating basis. Hatz quotes blocked ISO fuel stop power (IFN) for intermittent loading per ISO 3046-1, with separate figures for variable and constant speed and for less regulated markets. The data sheet gives derating of about 1 percent per 100 m above 100 m altitude and about 4 percent per 10 degrees C above 25 degrees C, which matters for hot sites, and the power drawn by the charging alternator must be added to the machine demand.
Before ordering, confirm the exact model code, shaft form, starting method (recoil or electric, 12 V or 24 V), mechanical or electronic control, the emission certificate your market needs and the installation dimensions and permitted inclination. Drawings in PDF and DXF are available from the manufacturer.

Frequently Asked Questions
What does the E in 1B30E mean?
It marks the Hatz E1 electronically controlled version, with electronic injection and a J1939 CAN interface. The data sheet lists the 1B30E, 1B30VE and 1B50E as E1 engines, and the 1B30VE has a vertical crankshaft.
How much power does the 1B30 deliver?
The data sheet shows 4.6 kW (6.2 hp) at 3000 rpm for the mechanical 1B30 on the variable-speed IFN basis. Ratings depend on speed, duty and market, so check the full performance table for your case.
Is the 1B30 air-cooled or liquid-cooled?
Air-cooled. The B-Series is an air-cooled single-cylinder four-stroke diesel with direct injection, and the data sheet lists the cooling air needed at 3000 rpm for installation planning.
How does altitude and heat affect power?
The data sheet states power reduction per ISO 3046-1 of about 1 percent per 100 m above 100 m and about 4 percent per 10 degrees C above 25 degrees C ambient.
What should I send to request a quotation?
The model code (for example 1B30 or 1B50E), shaft form, recoil or electric start with voltage, mechanical or electronic control, emission requirement and quantity.
