WinGD is a pioneer in modern dual-fuel technology for two-stroke marine engines, with LNG-fuelled engines in operation since 2016. The well-established X-DF engines series offers a range of benefits over other dual-fuel engine concepts.

The matrix A is sometimes known as the Jacobian matrix, and the linear transformation that associates to the increment Δx ∈ R n the vector AΔx ∈ R m is, in this general setting, known as the differential df(x) of f at the point x.

X-DF engines set the standard for low-pressure, dual-fuel LNG technology in two-stroke marine engines. Designed for efficiency and delivering exceptional operational control, compliance capability and cost advantages, X-DF engines have achieved millions of running hours since their introduction in 2016.

2020年10月21日 · X-DF two-stroke dual-fuel engines technology - Efficient solutions that deliver clear results. With the shipping industry facing more stringent environmental legislation with increasing operational costs, we would like to share our knowledge on environmental-friendly and efficient solutions.

This scientific visualization depicts a flight through the galaxies in the Hubble eXtreme Deep Field (XDF). Using measured and estimated distances for approximately three thousand galaxies,...

2018年5月12日 · df[['x']] — index/slice a single-column DataFrame having only one column named 'x'. Returns pd.DataFrame df.x — dot accessor notation, equivalent to df['x'] (there are, however, limitations on what x can be named if dot notation is to be successfully used).

Free derivative calculator - differentiate functions with all the steps. Type in any function derivative to get the solution, steps and graph.

X and Particulate Matter (PM) are a serious hazard to human health and can be most effectively reduced with X-DF propulsion! Extract from the latest WHO report, 02.05.2018: “In 2016, 91% of the world population was living in places where the …

2025年3月9日 · The results confirm that methane reductions from new X-DF engines with VCR technology deliver similar ship greenhouse gas (GHG) emissions to high-pressure dual-fuel technologies, while...

2025年1月27日 · The X-DF-A engine platform merges diesel-cycle technology with “innovative” ammonia injection and combustion technologies, aiming to control and minimise emissions. The ongoing single-cylinder tests are required for the “rapid” validation of the ammonia combustion system and optimising “emissions and performance”.
