  • HEAVY-DUTY DIESEL DOCKING STATION:Docking-station dynamometer simplifies and speeds engine testing

Land & Sea’s DYNOmite diesel dynamometers and custom industrial engine-testing systems are affordable, state-of-the-art dynos. All feature sophisticated data-acquisition electronics and incredibly powerful software packages – at a price/performance ratio formerly unheard of for professional, computerized dynamometers.

“Custom designs… simplify any industrial testing project!”

Specs Catalog Selector
Industrial-duty AC dynamometer systems, similar to this 800 Hp gasoline-engine installation, are also available for high-end diesel testing programs – and they include motoring capabilities.

Typical diesel dynos include: 19" heavy-duty toroidal water-brake or large eddy-current absorber, S-beam electronic torque transducer, high-flow manual (or optional electronic) engine load control, DYNOmite data-acquisition computer, rigid-frame engine test stand, wall (or stand) mounted control console, absorber to engine-block mounting adapter, heavy-duty input shaft, calibration arm, stainless-braided hoses, and full-function data wiring harness. See Specifications or Models and Prices pages.

DYNO-MAX dynamometer control software screen.DYNO-MAX dynamometer software graph.DYNO-MAX™ software option creates a full engine dynamometer lab console on your Windows PC. Features include: real-time trace graph display, adjustable limit warnings, voice alarms, pushbutton controls, user configurable analog and/or digital gauge ranges… along with advanced data tools and reporting functions. (Call or click for full list of features.)

Integrate your Windows PC using DYNO-MAX, together with our appropriate automated electronic load and throttle control hardware options, for keyboard dyno control. Without special programming you can easily execute many complex break-in or endurance simulations and custom engine test cycles.

DYNOmite data-acquisition electronics eliminate paper and pencil data logging – automatically recording true Hp, torque, RPM, elapsed time, etc. at up to 1,000 readings per second (per channel). It can apply inertia compensation and SAE atmospheric correction factors.

Instant test results display on either your DYNO-MAX-equipped PC or the optional portable DYNOmite LCD. Either configuration can output reports to your compatible printer (an optional ASCII thermal printer is available for portable operation).

“1500” heavy-duty toroid 26”; water-brake absorber with diesel torque-tube mount (shown next to 7”; absorber for comparison). Also available in Siamese-rotor, “3000,” and super-capacity (10,000 ft-lb) tandem configurations.

Engine test stand options include our standalone mobile frame type with its SAE bell-housing torque tube-mounted absorber – or the docking cart and station design (shown above). Both configurations feature a rugged tubular steel frame (with heavy-duty locking casters for easy in-shop mobility). Mounting options include using either heavy-duty fixed engine plates or adjustable leveling jack screws.

Water-cooled disk-brake absorbers are well suited to low- RPM, high-torque applications. A typical example is this diesel dynamometer, used for developing governors.

Block mounting adapters are available with torque tubes that couple the absorber to many popular Cummins, Caterpillar, etc. diesel engines. Their unique sealed-bearing design transmits no torque back to your engine stand (or shipping pallet). Bell-housing plates can be field adapted to other applications.

Heavy-duty solid stainless shafts are used in both our single-rotor and our Siamese-rotor 19" or 26" toroidal flow diesel absorbers. All the shafts and U-joints are heat treated – for longer life under the extreme torque loads of diesel engine testing cycles.

Precision torque transducers all use temperature-compensated full-bridge strain gauges. Environmentally sealed industrial S-beams, load cells, or torque tubes measure the precise shaft torque, allowing the data-acquisition system to accurately calculate repeatable real-time horsepower. Pushbutton, semi-automatic zero-offset calibration is a standard feature. The software even provides support for bi-directional torque readings – for testing counter-rotation engines.

Diesel dynamometers with tandem, 19" or 26" Siamese-rotor toroidal-flow water-brake absorbers, available to over 6,000 horsepower and 10,000 foot-pounds of torque.

4,000 foot-pound* and 2,000 Hp* capacity using our 19" heavy-duty dual-stator water-brake absorber (with Siamese rotor). Its advanced toroidal-flow design loads larger engines and delivers much better controllability than any older vane designs. (Other hydraulic, water, AC, and eddy-current absorber combinations are available to test engines from 1 to over 10,000 Hp.)

Sophisticated data-acquisition features that include: Smart Record™, data dampening, spike filtering, playback-data time averaging, atmospheric correction, auto-zeroing, instant playback, and integral rev-limiter.

DYNO-mite Diesel Dynamometer engine-endurance testing.

Load engines indefinitely, not limited to only a few seconds of flash inertial acceleration. (Water-brake absorbers require 5 gpm for every 100 continuous Hp.)*

“Pro” console upgrade includes a genuine Intel®-equipped Dell™ PC and a 17" high-resolution LCD monitor. It is optimized for DYNO-MAX’s real-time color graphics. (See specifications table for a longer list of features.)

Reduce field service problems by getting it right the very first time, while improving customer satisfaction. Uncovering turbo or injection system malfunction is no longer trial and error.

Sample engine-dynamometer cell layout. Low-cost and rapid installation are just two benefits of the standalone version’s unique design. For many applications this configuration allows testing right on the engine’s shipping crate. An expensive dyno cell is often not even required.

Easy test set-ups by mechanics and technicians with no dyno experience. Get quick horsepower plots of the entire torque vs. RPM curve. No prior experience with computers is needed. It can take less than an hour to install, test, and output report data with the DYNOmite. Just mount the absorber and torque-tube adapter plate assembly onto your engine’s bell-housing (or couple a rolling cart-mounted engine to its docking station), hook up the wiring and hoses, and begin testing.

Just a couple of the available accessories include digital output five-gas exhaust analyzers (not shown) and direct- mount smoke-opacity meters (above). Sample water-brake absorber plumbing.

Automated load control is available with the optional electronic auto-load servo (high or ultra-flow) control valve. It replaces the standard manual-load control unit. Just push the buttons to select the operating RPM, or set a sweep rate and allow the DYNOmite’s advanced PID algorithms to run the whole test. The computer logs all data automatically. (Simultaneous electronic throttle control, via DYNO-MAX, is also an available option.)

Advanced options including: thermostatically controlled cooling towers, fuel-flow and airflow turbines, blowby sensors, weather station (for automatic atmospheric data), EGT (exhaust-gas temperature) thermocouple kits, pressure transducers, fully digitally integrated five-gas exhaust analyzers, direct-mount smoke-opacity meters, temperature thermistors, auto-load and electronic throttle control, and more.

*Approximate; continuous capacities depend on selected absorber and test speed. Air-cooled absorber loads are rotor temperature dependent. Water brake power capacities are RPM dependent and assume a minimum water supply of 1 gpm @ 30 to 60 psi for every 20 continuous Hp. Call Land & Sea, Inc. at (603) 226-3966 for the approximate capacity of any specific test configuration.
